Edition • 2023-07-21T16:29:19+02:00 Isolating switching amplifier 2-channel IM1-22EX-T The 2-channel IM1-22EX-T isolating switching amplifier is equipped with intrinsically safe in- put circuit. Sensors according to EN 60947-5-6 (NAMUR) or potential-free contact transmitters can be connected to the device. The output circuits feature 2 potential-free and short-circuit proof transistors. Via six switches on the front, you can set the operating behaviour for each channel sepa- rately (work or quiescent current behaviour, i.e. NO/NC) as well as switch wire-break (WB) and short-circuit monitoring (SC) on and off. When using mechanical contacts, wire-break and short-circuit monitoring must be switched off or the contacts must be wired to resistors (II) (see circuit diagram). The Pwr LED lights green to indicate opera- tional readiness. The 2-color LEDs 1 and 2 light yellow to indicate the switching status of the associated output. In the event of an input circuit error, the 2-color LED of the as- signed faulty input turns red, with the input cir- cuit monitoring switched on. Thereupon the associated output transistor is blocked. ■ 2 transistor outputs ■ Output mode adjustable (NO/NC mode) ■ Input circuits monitored for wire-break/ short-circuit (ON/OFF switchable) ■ SIL 2 ■ Complete galvanic isolation ■ Input reverse-polarity protected ■ ATEX, IECEx, UL, CFMUS, CSA, TR CU, NEPSI, KOSHA, TIIS, CCOE, INMETRO ■ Installation in zone 2
