Sensors according to EN 60947-5-6 (NAMUR)
or potential-free contacts can be connected
to the IM12-DI01-2S-2R-0/24VDC/CC isolating switching amplifier. The device can be installed in zone 2;
a DIP switch allows toggling between 2-channel or 1-channel operating mode with signal
doubling. The output circuits are equipped
with two changeover relays. 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 relay
of the corresponding output circuit drops out.

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.
