SNAP Isolated Analog Input Modules Features Description SNAP I/O isolated analog input modules provide two or more channels isolated from each other, thereby eliminating problems caused by ground loop currents. These isolated analog modules are part of Opto 22's SNAP PAC System and mount on SNAP PAC racks with an I/O processor (brain or onthe-rack controller). SNAP isolated analog input modules are compatible with all SNAP PAC brains and rack-mounted controllers, including Wired+WirelessTM. Since many SNAP analog input modules are softwareconfigurable and handle a wide variety of signal levels, a small number of modules can support a wide range of input requirements. Modules provide high resolution for precise signal levels, and all SNAP analog modules are factory calibrated. Part numbers ending in -FM are Factory Mutual approved. Dimensional drawings start on page 14. SNAP analog input modules have an on-board microprocessor to provide module-level intelligence, making them an ideal choice for original equipment manufacturers (OEMs). For more information about standalone SNAP analog modules, see the SNAP I/O Module Integration Guide (form 876). 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 (recommended torque: 4 inch pounds [0.45 Newton meters]). Notes for legacy hardware: Most isolated analog input modules can be used with SNAP Simple, SNAP Ethernet, SNAP Ultimate, and SNAP mistic brains such as the serial B3000, and with M-series or B-series mounting racks. For exceptions, see individual module descriptions. SNAP Isolated Analog Input Modules from ground-loop problems even on grounded devices connected to channels on the same module. Transformer isolation prevents ground loop currents from flowing between field devices and causing noise that produces erroneous 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.

With the connection of a single 24 V power supply, these modules source 24 V for two 4-20 mA loops. The two channels and their loop sources are isolated from each other; they do not share any field connection. The isolation allows you to independently wire one channel to a loop with an external power supply and the other channel to a loop powered through the module. In addition, each loop sourced through the module is current limited so that an external fault on one loop will not affect the other.

More About Opto 22 Products Opto 22 develops and manufactures reliable, easy-to-use, open standards-based hardware and software products deployed worldwide. Industrial automation, process control, building automation, industrial refrigeration, remote monitoring, data acquisition, Industrial Internet of Things (IIoT), and information technology applications all rely on Opto 22. Control programming includes both easy-to-learn flowcharts and optional scripting. 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 one SoftPAC software-based controller, OptoOPCServer, OptoDataLink, options for controller redundancy or segmented networking, and support for legacy Opto 22 serial misticTM I/O units. groov SNAP PAC Brains Monitor and control your equipment from anywhere using your smartphone or tablet with groov. 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. 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. Support is available in English and Spanish by phone or email, Monday-Friday, 7 a.m. to 5 p.m. PST. Additional support is always available on our website: how-to videos, OptoKnowledgeBase, self-training guide, troubleshooting and user's guides, and OptoForums. In addition, hands-on training is available for free at our Temecula, California headquarters, and you can register online. Purchasing Opto 22 Products Opto 22 products are sold directly and through a worldwide network of distributors, partners, and system integrators.
