DATA SHEET Form 1066-180808 PAGE 1 SNAP ANALOG OUTPUT MODULES Features > > > > > > > > Resolution = 0.004% of nominal range Rugged packaging Convenient pluggable wiring Powered by a single 5-volt supply Factory calibrated; no user adjustment necessary Out-of-range indication Operating temperature -20 C to 70 C Accepts up to 22 to 14 AWG wire DESCRIPTION SNAP I/O analog output modules are part of Opto 22's SNAP PAC System. They mount on SNAP PAC racks along with other I/O modules and a SNAP PAC brain or R-series controller. These software-configurable output modules handle a wide variety of signal levels. Most provide dual-channel packaging. All SNAP analog modules are factory calibrated. Part numbers ending in -FM are Factory Mutual approved. SNAP analog output modules have an on-board microprocessor to provide module-level intelligence, which makes them an ideal choice for Original Equipment Manufacturers (OEMs). For additional information about the stand-alone operation of SNAP analog modules, please refer to the SNAP I/O Module Integration Guide (form 0876). SNAP Analog Output Modules readings. Ground loop currents are caused when two grounded field devices share a connection, and the ground potential at each device is different. Isolation also provides protection for sensitive control electronics from industrial field signals. IMPORTANT: Since most SNAP dual-channel analog output modules provide two single-ended output channels with a common reference, these dual channels are transformer and optically isolated from other modules, but not from each other. However, SNAP-AOA-23-iSRC, SNAP-AOD-29, and SNAP-AOD-29-HFi do have channel-to-channel isolation. Part Numbers Part SNAP-AOA-23 Description Dual-channel analog output, current loop, 4-20mA Isolated dual-channel analog SNAP-AOA-23-iSRC output, current loop, 4-20 mA, SNAP-AOA-23-iSRC-FM* with loop sourcing SNAP racks have a retention rail locking system. Use two 4-40 by 1/2-inch standard machine screws to hold each module securely in position on the SNAP rack. Specifications and wiring diagrams are in module descriptions starting on page 2. Dimensional drawings begin on page 15. See pg 4 pg 5 SNAP-AOA-28 Dual-channel analog output, current loop, 0-20 mA pg 9 SNAP-AOA-3 Single-channel current output, 4-20mA pg 2 pg 10 Notes for legacy hardware: Most SNAP analog output modules can also be used with legacy SNAP Simple, SNAP Ethernet, and SNAP Ultimate brains and with serial SNAP brains such as the B3000. These modules can be mounted on SNAP B-series or M-series racks. Exceptions are noted in individual module descriptions.

On most dual-channel modules, the two channels are not isolated from each other. Exceptions: SNAP-AOA-23-iSRC, SNAP-AOD-29, and SNAP-AOD-29-HFi have two isolated channels.

DATA SHEET Form 1066-180808 PAGE 11 8-CHANNEL MULTIFUNCTION VOLTAGE/CURRENT OUTPUT Part Number SNAP-AOVA-8 The SNAP-AOVA-8 is an analog output module with 8 channels, individually configurable for any one of six voltage or current output ranges: Voltage Self-sourcing Current 0 to 5 VDC 0 to 10 VDC -5 to +5 VDC -10 to +10 VDC 4 to 20 mA 0 to 20 mA Each range has 4096 counts (12 bits) of resolution. The SNAP-AOVA-8 requires a 24 VDC excitation voltage brought in through the field connector on the top of the module. This voltage is internally isolated with transformer and digital data isolators, and then used to source all channels. Because all current is sourced from within the module using the 24 VDC excitation, current outputs are self-sourcing and cannot be used with an external loop supply or in loops that are loop-powered or have a self-sourcing device in the loop. Each channel is individually current or voltage limited and not affected by opens or shorts on adjacent channels. Connect both wires Specifications: SNAP-HD-20F6 Description 8-channel analog multifunction output, voltage or current 6 ft. (1.8 m) wiring cable for SNAP-AOVA-8 module, with flying leads (required) from the module, so that a change in output on one channel will not affect another channel. All negative output terminals on the module are tied together internally. To prevent ground loops, use loads with isolated signal inputs or use devices with the same power source, so they have a common ground. To wire the module, a 6-foot-long SNAP-HD-20F6 cable is required. The cable has a 20-pin connector at the module end and flying leads for wiring to field devices. See wiring information on page 14. You can also use a SNAP-TEX-32 breakout board for wiring convenience. See the SNAP TEX Cables & Breakout Boards Data Sheet (form 1756) for more information. The SNAP-AOVA-8 requires a SNAP PAC brain or rack-mounted controller with firmware version R9.4b or higher. It cannot be used with legacy controllers or brains.

More about Opto 22 PRODUCTS * Opto 22 develops and manufactures reliable, easy-to-use, open standards-based hardware and software products. Industrial automation, process control, building automation, industrial refrigeration, remote monitoring, data acquisition, and industrial internet of things (IIoT) applications worldwide all rely on Opto 22. groov EPIC(R) System Opto 22's groov Edge Programmable Industrial Controller (EPIC) system is the culmination of over 40 years of experience in designing products for the automation industry. groov EPIC gives you an industrially hardened system with guaranteed-for-life I/O, a flexible Linux(R)-based controller with gateway functions, and software for your IIoT application or any application. groov EPIC I/O Ignition Edge(R) from Inductive Automation(R), with OPC-UA drivers to Allen-Bradley(R), Siemens(R), and other control systems, and MQTT/Sparkplug communications for efficient IIoT data transfer groov Edge Appliance Visualization, data handling, and connectivity in a compact, industrial box: that's the groov Edge Appliance. Included are: * groov View for building and viewing operator interfaces on PCs and mobile * Node-RED for building simple logic flows * Ignition Edge(R) from Inductive Automation(R), for OPC-UA drivers and MQTT/Sparkplug IIoT communications Older products From solid state relays (our first products) to world-famous G4 and SNAP I/O, to SNAP PAC controllers, Opto 22 products last a long time. You can count on us to give you the reliability and service you expect. I/O provides the local connection to sensors and equipment. groov I/O offers up to 24 channels on each I/O module, with a spring-clamp terminal strip, integrated wireway, and swingaway cover. QUALITY Founded in 1974, Opto 22 has established a worldwide reputation for high-quality products. All are made in the U.S.A. at our manufacturing facility in Temecula, California. Opto 22 I/O is so reliable, we can afford to guarantee it for life. groov I/O is hot swappable, UL Hazardous Locations approved, and ATEX compliant. Because we test each product twice before it leaves our factory rather than testing a sample of each batch, we can guarantee most solid-state relays and optically isolated I/O modules for life. groov EPIC Controller The heart of the system is the groov EPIC controller. It handles a wide range of digital, analog, and serial functions for data collection, remote monitoring, process control, and discrete and hybrid manufacturing. In addition, the EPIC provides secure data communications among physical assets, control systems, software applications, online services, and more, both on premises and in the cloud. Configuring and troubleshooting I/O and networking is easier with the EPIC's integrated high-resolution touchscreen. Authorized users can see your groov View HMI locally on the touchscreen or on a monitor connected via the HDMI or USB ports. groov EPIC Software Software includes: * Flowchart-based PAC Control for control programming, or build your own custom application with optional secure shell access * groov View for building and viewing your own deviceindependent HMI * Node-RED for creating simple logic flows from pre-built nodes OPTO 22 * www.opto22.com 43044 Business Park Dr. Temecula, CA 92590-3614 FREE PRODUCT SUPPORT Opto 22's California-based Product Support Group offers free, comprehensive technical support for Opto 22 products from engineers with decades of training and experience.
