Isolating transducer IM12-AI01-1I-2IU-HPR/24VDC/CC, HART, 4-20mA splitter, Power bridge, SIL2

IM12-AI01-1I-2IU-HPR/24VDC/CC is a 1-channel TURCK isolating transducer for HART 2-wire transmitters. The 4...20 mA input is passed 1:1 to two isolated outputs (splitter), and HART communication runs bidirectionally through output O1.

• Channels: 1 input, 4...20 mA, transmitter supply 17 V / 20 mA
• Outputs: 2 x 4...20 mA (source or sink) or 1...5 V; HART on O1 only
• Accuracy: ≤0.05 % of full scale
• Supply: 10...30 V DC via terminals or Power bridge, ≤3.8 W
• Housing: polycarbonate/ABS, 120 x 12.5 x 128 mm, DIN rail (NS35), removable spring-type terminals
• Environment: IP20, -25...+70 °C

Used where one transmitter signal from a hazardous area is needed by two systems, for example a control system and a separate safety system. Wire break (< 3.5 mA) and short circuit (> 22 mA) are passed to the outputs as < 3.5 mA or < 0.875 V. The Power bridge also carries a collective fault signal; its connector is included.

Approvals: ATEX, cULus; for use in ATEX Zone 2. SIL 2.
