DATA SHEET SNAP Isolated Analog Input Modules Form 1182-150113 SNAP Isolated Analog Input Modules Features Channel-to-channel isolation Rugged packaging and convenient pluggable wiring. Accepts 22 to 14 AWG wire. Factory calibrated no user adjustment necessary SNAP Isolated Analog Input Modules Out-of-range indication Channel-to-channel isolation gives you complete freedom Operating temperature -20 C to 70 C from ground-loop problems even on grounded devices connected to channels on the same module. Description Transformer isolation prevents ground loop currents from flowing between field devices and causing noise that SNAP I/O isolated analog input modules provide two or more produces erroneous readings. Ground loop currents are channels isolated from each other, thereby eliminating caused when two grounded field devices share a connection, problems caused by ground loop currents. These isolated and the ground potential at each device is different. analog modules are part of Opto 22s SNAP PAC System and mount on SNAP PAC racks with an I/O processor (brain or on- Isolation also provides protection for sensitive control the-rack controller). SNAP isolated analog input modules are electronics from industrial field signals. compatible with all SNAP PAC brains and rack-mounted controllers, including Wired+Wireless . Since many SNAP analog input modules are software- configurable 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 Part Numbers signal levels, and all SNAP analog modules are factory Part Description Pg calibrated. Part numbers ending in -FM are Factory Mutual approved.

An ideal input is the 5-amp secondary of a standard current transformer used to monitor AC line current. These modules may also be used to monitor AC current to greater than a 100-amp range, using a current transformer of suitable ratio. The SNAP-AIARMS-i-FM module is Factory Mutual approved. The two channels are isolated from each other they do not share any field connection. These modules are ideal for differential current measurements.
