Edition • 2023-07-21T16:29:21+02:00 Isolating switching amplifier 2-channel IM12-22EX-R The 2-channel IM12-22EX-R isolating switch- ing amplifier is equipped with intrinsically safe input circuits. Sensors according to EN 60947-5-6 (NAMUR) or potential-free contact transmitters can be connected to the device. The output circuits feature 2 relays, each with 1 NO contact. You can toggle between working or closed current, resp. NO or NC mode via three switches at the front. The switching state of channel 1 is thereby transmitted to the outputs 1 and 2. The Pwr LED lights green to indicate opera- tional readiness. LED 1 lights yellow to indi- cate the switching status of the output. ■ 2 relay outputs (NO) ■ Output mode adjustable (NO/NC mode) ■ Multiplexing of signals possible ■ Complete galvanic isolation ■ Input reverse-polarity protected ■ ATEX, IECEx, cUL, cFM, CSA, TR CU, NEPSI, KOSHA, TIIS, CCOE, INMETRO ■ Installation in zone 2
