Operating temperature -20 C to 70 C Transformer isolation prevents ground loop currents from Accepts up to 22 to 14 AWG wire flowing between field devices and causing noise that produces erroneous readings. Ground loop currents are caused when two grounded field devices share a connection, Description and the ground potential at each device is different. SNAP I/O analog output modules are part of Opto 22s SNAP Isolation also provides protection for sensitive control PAC System. They mount on SNAP PAC racks along with other electronics from industrial field signals. I/O modules and a SNAP PAC brain or R-series controller, either a standard wired or a Wired+Wireless model. IMPORTANT: Since most SNAP dual-channel analog output modules provide two single-ended output channels with a These software-configurable output modules handle a wide common reference, these dual channels are transformer and variety of signal levels. Most provide dual-channel packaging. optically isolated from other modules, but not from each All SNAP analog modules are factory calibrated. Part numbers other. However, SNAP-AOA-23-iSRC, SNAP-AOD-29, and ending in -FM are Factory Mutual approved. SNAP-AOD-29-HFi do have channel-to-channel isolation. SNAP analog output modules have an on-board Part Numbers microprocessor to provide module-level intelligence, which makes them an ideal choice for Original Equipment Part Description See Manufacturers (OEMs). For additional information about the Dual-channel analog output, SNAP-AOA-23 pg 4 stand-alone operation of SNAP analog modules, please refer current loop, 420mA to the SNAP I/O Module Integration Guide (Opto 22 form 876). Isolated dual-channel analog SNAP-AOA-23-iSRC output, current loop, 420 pg 5 SNAP racks use a retention rail locking system that holds SNAP-AOA-23-iSRC-FM* mA, with loop sourcing modules securely to the rack.
