Isolating switching amplifier 2-channel IM1-22EX-T Edition • 2012-08-16T23:46:10+02:00 1 / 4 TURCK Inc. ñ 3000 Campus Drive Minneapolis, MN 55441-2656 ñ Phone: 763-553-7300 ñ Application Support: 1-800-544-7769 ñ Fax 763-553-0708 ñ www.turck.com The dual-channel isolating switching amplifier IM1-22EX-T is equipped with an intrinsically safe input circuit. Sensors according to EN 60947-5-6 (NA- MUR) can be connected to the device or po- tential-free contactors. The output circuits feature two potential-free and short-circuit protected transistors. Six front panel switches are available to set the output mode separately for each channel (NO/NC mode), as well as to enable/disable wire-break (WB) and short-circuit (SC) moni- toring separately. When using mechanical contacts, wire-break and short-circuit monitoring must be switched off or the contact must be wired with resistors (II) (see circuit diagram). The green LED indicates operational readi- ness. The switching status of the correspond- ing output is indicated yellow by the two col- or LED. In the event of input circuit errors the dual color LED changes to red, provided the input circuit monitoring function is activated. Thereupon the related output transistor is de- energized. ■ Intrinsically safe input circuits Ex ia ■ Installation in zone 2 ■ FM, NEPSI ■ SIL2 ■ Application area acc. to ATEX: II (1) G, II (1) D; II G 3 ■ 2 transistor outputs ■ Adjustable signal flow direction (NO/ NC) ■ Input circuit monitoring of wire-break/ short-circuit (ON/OFF switchable) ■ Removable terminal blocks ■ Galvanic separation of input circuits, output circuits and power supply
