Analog I/O Modules Lead Isolated Lives

Providing full isolation between devices interfacing with them, the SNAP-AIARMS-i, SNAP-AIVRMS-i, SNAP-AIMA2-i, and SNAP-AOA-23-iSRC two-channel analog I/O modules address a range of ac/dc measurement applications. The SNAP-AIARMS-i handles current measurement and the SNAP-AIVRMS-i measures voltage. Alternately, the SNAP-AIMA2-i monitors very-low currents while the SNAP-AOA-23-iSRC provides industrial-centric output current. The SNAP-AIARMS-i accepts inputs from 0 to 10ARMS and provides early detection of current spikes and the SNAP-AIVRMS-i manages voltage inputs from 0 to 250 Vac/dc. For low-current apps, the SNAP-AIMA2-i eyes a range of ±1 mA. Lastly, the SNAP-AOA-23-iSRC provides output currents from 4 mA to 20 mA and features integrated isolated current loop sourcing. Support comes by way of comprehensive software suites that include control programming, debugging, HMI development, OPC connectivity, and utilities. Single-unit price for each module is $265.
