Edition • 2023-07-21T16:27:32+02:00 Analog Signal Isolator 2-channel IM35-22EX-HI/24VDC The 2-channel IM35-22EX-HI/24VDC sig- nal isolator is designed to transmit the nor- malized current signal galvanically isolat- ed 1:1 from the non-Ex area to the Ex-area. In addition to the analog signal, also digital HART communication signals can be transmit- ted bidirectionally. Typical applications are for example, the con- trol of I/P converters (at control valves for ex- ample) or indicators in the Ex-area. The actuators are connected to the output ter- minals 1/2 and 4/5. Handheld terminals [HHT] can be connected to the output and input ter- minals 7/10 and 8/9. In addition, the removable terminal blocks are equipped with 2 mm test sockets for signal control. ■ Intelligent actuators supplied via HART communication interface ■ Input circuits: 0/4…20 mA ■ Output circuits: 0/4…20 mA, intrinsically safe ■ SIL2 ■ Removable terminal blocks, screwable, with 2 mm test box ■ Complete galvanic isolation ■ Input reverse-polarity protected ■ ATEX, IECEx, UL, CFMUS, TR CU, KOSHA, CCOE ■ Installation in zone 2
