Sensors according to EN 60947-5-6 (NAMUR)

or potential-free contacts can be connected

to the IM12-DI03-1S-1NAM1R-0/24VDC NAMUR repeater. The device can be installed

in zone 2. The output circuit is also equipped

with a relay output. The device complies with

the requirements of the 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. A LOW

level is then output at both outputs.

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 screw

terminals.
