SNAP Power Supplies Features Description SNAP power supplies provide the best source of AC or DC power for your Opto 22 SNAP PAC hardware. Packaged in a compact and sturdy housing, SNAP power supplies include a built-in fuse, an LED status indicator, and an ON/OFF power switch for ease of use. The SNAP-PS24 and SNAP-PS24U power supplies are designed for either of two purposes: * to provide primary power for a SNAP PAC S-series controller * to provide 24 volts of DC loop power for SNAP analog modules mounted on a SNAP PAC rack The SNAP-PS5, SNAP-PS5-24DC, and SNAP-PS5U power supplies are designed to provide 5 VDC power for a SNAP PAC rack with an I/O processor (SNAP PAC brain or R-series controller) and I/O modules mounted on the rack. The combination of a rack, processor, and modules is called an I/O unit. Opto 22 recommends using one SNAP power supply for each I/O unit and for each controller. Choose the power supply based on the load required for the I/O unit. See the power requirements tables starting on page 11 for help in determining the power supplies you need. Additional information on using power supplies can be found in the Opto 22 technical note Using Power Supplies with Opto 22 Systems (form #1271, available on our website, www.opto22.com). All SNAP power supplies except the SNAP-PS5-24DC require AC input power. The SNAP-PS5U and SNAP-PS24U accommodate a wide range of AC input voltages, from 100 to 250 VAC. The SNAP-PS5-24DC DC-to-DC power supply requires a 24 VDC input and is ideal for systems using DC backup power. AC or DC input power connections, as required by the model, are made to a removable terminal strip on top of the power supply. DC output power is then ready to be hooked up to the controller or rack using the attached wiring harness. SNAP power supplies work with Wired+WirelessTM PACs and I/O units as well as standard wired PACs and I/O. Notes for legacy hardware: SNAP power supplies are also compatible with Ethernet-based SNAP Ultimate, SNAP Ethernet, and SNAP Simple I/O, and with serial-based SNAP I/O units such as those with a B3000, SNAP-HA, or SNAP-B3000-MODBUS brain.

Copy the power requirements worksheet and complete one for each distributed I/O unit. Use a separate power supply for the field side of the I/O. Using the rack supply for field actuation and monitoring defeats the isolation the I/O module offers and therefore increases the chance of a ground loop within the control system. Additionally, a sudden change of current on the field side can cause undesirable voltage fluctuations that may interfere with the controller or I/O unit's operation. In addition, keep the following power recommendations in mind. For more help with power supplies, see Opto 22 form #1271, Using Power Supplies with Opto 22 Systems. Form 1120-090810 DATA SHEET Use a single power supply per rack PAGE 2 SNAP-PS5U In general, we recommend you use an independent, isolated, regulated power supply locally with each rack. Local isolated supplies offer these advantages: * Short supply conductors, which minimize losses * Power redundancy, so the failure of a single supply causes only a single rack failure, not a total system failure * Fewer voltage drops and ground loops (Voltage drops and subsequent ground loops may occur when power is distributed over a large system.) Power wiring guidelines * Use one power supply per I/O unit. * Use one power supply per controller. * Use 14 AWG wire. * SNAP power supplies have wires of limited length to minimize voltage drop. Do not extend the length of the wires. * If you power multiple I/O units or controllers from one power supply, use a star wiring topology. Do not daisy-chain power wiring from one device to the next.

PAGE 3 SNAP Power Supplies Wiring to a Standalone Controller 1. For a controller, check the controller's specifications in its data sheet or user's guide to make sure you have the correct power supply for the controller's requirements. 2. Follow directions in the controller's user's guide to wire the power supply to the controller. The power supply's red (or white-and-red) wire is the positive wire; the black (or whiteand-black) wire is the negative wire. Wiring to a SNAP I/O Unit 1. Using the power terminals on the SNAP mounting rack, attach the red wire to the "+" terminal and the black wire to the "-" terminal. 2. For the SNAP-PS5 (not illustrated): Using the removable input power connector on top of the power supply, apply 120 volts AC power between the two terminals marked "AC." The ground terminal should be connected to ground. 3. For the SNAP-PS5-24DC (not illustrated): Using the removable input power connector on top of the power supply, apply 24 volts DC power between the two terminals marked "DC." The ground terminal should be connected to ground. 4. For the SNAP-PS5U (illustrated below): Using the removable input power connector on top of the power supply, apply 100-250 volts AC power between the two terminals marked "AC." The ground terminal should be connected to ground.

More About Opto 22 Products SNAP PAC Brains Opto 22 develops and manufactures reliable, flexible, easy-to-use hardware and software products for industrial automation, remote monitoring, and data acquisition applications. SNAP PAC System Designed to simplify the typically complex process of understanding, selecting, buying, and applying an automation system, the SNAP PAC System consists of four integrated components: * SNAP PAC controllers * PAC ProjectTM Software Suite * SNAP PAC brains * SNAP I/OTM While SNAP PAC controllers provide central control and data distribution, SNAP PAC brains provide distributed intelligence for I/O processing and communications. Brains offer analog, digital, and serial functions, including thermocouple linearization; PID loop control; and optional high-speed digital counting (up to 20 kHz), quadrature counting, TPO, and pulse generation and measurement. SNAP I/O I/O provides the local connection to sensors and equipment. Opto 22 SNAP I/O offers 1 to 32 points of reliable I/O per module, depending on the type of module and your needs. Analog, digital, serial, and special-purpose modules are all mixed on the same mounting rack and controlled by the same processor (SNAP PAC brain or rack-mounted controller). Quality SNAP PAC Controllers Programmable automation controllers (PACs) are multifunctional, multidomain, modular controllers based on open standards and providing an integrated development environment. Opto 22 has been manufacturing PACs for many years. The latest models include the standalone SNAP PAC S-series and the rackmounted SNAP PAC R-series. Both handle a wide range of digital, analog, and serial functions and are equally suited to data collection, remote monitoring, process control, and discrete and hybrid manufacturing. SNAP PACs are based on open Ethernet and Internet Protocol (IP) standards, so you can build or extend a system without the expense and limitations of proprietary networks and protocols. PAC Project Software Suite Opto 22's PAC Project Software Suite provides full-featured and cost-effective control programming, HMI (human machine interface) development and runtime, OPC server, and database connectivity software to power your SNAP PAC System. These fully integrated software applications share a single tagname database, so the data points you configure in PAC ControlTM are immediately available for use in PAC DisplayTM, OptoOPCServerTM, and OptoDataLinkTM. Commands are in plain English; variables and I/O point names are fully descriptive. PAC Project Basic offers control and HMI tools and is free for download on our website, www.opto22.com. PAC Project Professional, available for separate purchase, adds OptoOPCServer, OptoDataLink, options for Ethernet link redundancy or segmented networking, and support for legacy Opto 22 serial misticTM I/O units. Founded in 1974 and with over 85 million devices sold, Opto 22 has established a worldwide reputation for highquality products. All are made in the U.S.A. at our manufacturing facility in Temecula, California. Because we do no statistical testing and each part is tested twice before leaving our factory, we can guarantee most solid-state relays and optically isolated I/O modules for life. Free Product Support Opto 22's Product Support Group offers free, comprehensive technical support for Opto 22 products. Our staff of support engineers represents decades of training and experience. Product support is available in English and Spanish, by phone or email, Monday through Friday, 7 a.m. to 5 p.m. PST. Free Customer Training Hands-on training classes for the SNAP PAC System are offered at our headquarters in Temecula, California.
