Sensors according to EN 60947-5-6 (NAMUR) or potential-free contacts can be connected to the IM12-DI01-2S-2PP-PR/24VDC/

CC isolating switching amplifier. The device is

equipped with two channels, but can also be

used as a splitter. The device can be installed

in zone 2. The output circuit is equipped with

2 push/pull outputs with a high cut-off frequency (15 kHz). The device can be powered from

a power bridge that also transmits a collective

fault signal. The device complies with the requirements of NE21.

The devices feature DIP switches on the

front. This allows to select between the output

mode, the input circuit monitoring, as well as

toggle between signal duplication and 1-channel operation. When using mechanical contacts, either line monitoring must be switched

off or the contact must be wired with resistors

(see wiring diagram).

The green LED indicates operational readiness. An error in the input circuit causes the

red LED to flash according to NE44. The output level then drops to below 1 V and the

common alarm output switches to conductive.

The device can be used in safety circuits up to

SIL2 (high and low demand according to IEC

61508).

The device is equipped with removable spring

type terminals.
