Edition • 2023-07-21T16:27:27+02:00 Isolating transducer 1-channel IM33-11-HI/24VDC The 1-channel HART isolating transducer IM33-11-HI/24VDC is designed to operate HART 2-wire transducers (III) and to trans- mit galvanically isolated signals. In addi- tion to the analog signals, also the digital HART communication signals can be transmit- ted bidirectionally. Alternatively, active 2-wire HART transmitters (II) and passive 3-wire HART transmitters (I) can be operated. The device features one input and one output circuit, each with 0/4…20 mA. A green LED indicates operational readiness. The input signals are transmitted 1:1 without interference and made available at the output. The removable terminal blocks feature test sockets (Ø 2 mm) for connection of a HART handheld. ■ Power supply of 2-wire measuring trans- ducers with HART communication as well as connection to active 2-wire and passive 3-wire transmitters ■ Input circuit: 0/4…20 mA ■ Output circuit: 0/4…20 mA ■ SIL2 ■ Removable terminal blocks, screwable, with 2 mm test box ■ Complete galvanic isolation ■ Input reverse-polarity protected ■ TR CU
