Sensors according to EN 60947-5-6 (NAMUR)
or potential-free contacts can be connected to
the IM12-DI03-1S-1NAM1T-PR/24VDC NAMUR repeater. This can be installed in zone
2. The output circuit is also equipped with a
transistor output. The device can be powered
from a power bridge that also transmits a collective fault signal. 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 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 screw
terminals.
