The SNAP-AIMA provides two channels of -20 mA to +20 mA analog current input. The module does not supply loop excitation current. Although the two channels are not isolated from each other, the module is transformer isolated and optically isolated from other modules and devices. SNAP analog input modules are part of Opto 22’s SNAP PAC System. These modules mount on a SNAP PAC rack with a SNAP PAC brain or R-series controller, either a standard wired model or a Wired+Wireless model. SNAP analog input modules have an onboard microprocessor to provide module-level intelligence, which makes them an ideal choice for Original Equipment Manufacturers (OEMs).Underwriters Laboratory, Factory Mutual, IEC 950: 1991-09, 89/336/EEC, 2002/95/EC, Defense Federal Acquisition Regulation Supplement
