The 2-channel HART®

isolating transducer

IM33-22EX-HI/24VDC is designed to operate intrinsically safe HART®

2-wire transducers (III) in the Ex area and to transmit the

measured signals to the non-Ex area. In addition to the analog signals, also the digital

HART®

communication signals can be transmitted bidirectionally.

Alternatively, active 2-wire HART®

transmitters

(II) and passive 3-wire HART®

transmitters (I)

can be operated.

The device features 0/4…20 mA input and

output circuits. A green LED indicates operational readiness.

The input signals are transmitted 1:1 without

interference and made available at the outputs in the non-Ex area.

The removable terminal blocks feature test

sockets (Ø 2 mm) for connection of a HART®

handheld.
