SNAP Quadrature Input Module Features 4,000 Vrms optical isolation Built-in LED status indicators 4 times encoder resolution Input signals in 4-24 VDC range The SNAP-IDC5Q quadrature input module is part of the SNAP PAC System. It mounts on a SNAP PAC rack and is designed to allow a SNAP PAC brain or R-series controller with high-speed counting capability (either a standard wired model or a Wired+WirelessTM model) to resolve two axes of rotating position information from quadrature encoder devices. The module outputs a pulse to the SNAP PAC processor upon each change in quadrature state. The processor counts the module output pulses and keeps track of the direction and position. The SNAP-IDC5Q can be used with most quadrature devices, including transducers with TTL, CMOS, and open collector outputs. All inputs are isolated from each other and do not share any common connections. 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. Module Operation For each axis, the SNAP-IDC5Q quadrature module converts a quadrature signal to a stream of pulses that is sent to the I/O processor on one of two input channels. The rotation direction of the encoder determines which output is used. The position count is incremented when the signal into the A channel leads the signal into the B channel. It is decremented when the signal into the B channel leads the signal into the A channel. Since the I/O processor (brain or on-the-rack controller) has a maximum input count rate, the maximum allowable RPM at which the encoder may turn is related to the number of cycles per turn that the encoder outputs.

DATA SHEET Part Number Form 1053-160919 Notes for legacy hardware: The SNAP-IDC5Q is also compatible with Ethernet-based SNAP-B3000-ENET and SNAP-UP1-ADS brains, as well as B3000, B3000-B, and B3000HA brains, which use the mistic protocol. From a mounting standpoint the module is treated as a standard SNAP I/O digital module, which means it can be installed only in the first eight positions (0-7) of larger SNAP B-series racks.

Build your own mobile app easily--just drag, drop, and tag. No programming or coding. Visit groov.com for more information and your free trial. 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, local PID loop control, watchdog, totalizing, and much more. SNAP PAC System Developer- and IIoT-ready, the SNAP PAC System connects physical assets to databases and applications using open standards. The SNAP PAC System consists of four integrated components: * SNAP PAC controllers * PAC ProjectTM Software Suite * SNAP PAC brains * SNAP I/OTM SNAP PAC Controllers SNAP PAC programmable automation controllers handle a wide range of digital, analog, and serial functions for data collection, remote monitoring, process control, and discrete and hybrid manufacturing. For IIoT applications and easier integration with company systems, standalone and rack-mounted SNAP PACs include a built-in HTTP/HTTPS server and RESTful API (application program interface). The REST API gives you secure, direct access to I/O and variable data using your choice of programming languages. No middleware, protocol converters, drivers, or gateways needed. Based on open Ethernet and Internet Protocol (IP) standards, SNAP PACs make it easier to 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 offers full-featured, costeffective control programming, HMI (human machine interface), OPC server, and database connectivity software. 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. Analog, digital, and serial modules are mixed on one mounting rack and controlled by a SNAP PAC brain or rack-mounted PAC. 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. Because we test each product twice before it leaves our factory, rather than only testing a sample of each batch, we can guarantee most solid-state relays and optically isolated I/O modules for life.
