The 1-channel HART?

isolating transducer

IM33-12Ex-HI/24VDC is designed to operate intrinsically safe HART?

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

measured signal 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 1 input and 2 output circuits laid out for 0/4…20 mA. A green LED indicates operational readiness.

The input signal is transmitted 1:1 without interference and made available at the output in

the non-Ex area. The HART?

signal is transmitted to output 1.

The removable terminal blocks feature test

sockets (? 2 mm) for connection of a HART?

handheld.
