Sensors according to EN 60947-5-6 (NAMUR)
or potential-free contacts can be connected
to the IMX12-DI03-1S-2R-SPR/24VDC/CC
isolating switching amplifier. The device is
equipped with intrinsically safe input circuits
and can be installed in zone 2. The device
can be switched between 1-channel operation
with signal doubling or 1-channel operation
with alarm message output using DIP switches. The output circuits are equipped with two
changeover relays. 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 relay of the corresponding output circuit drops
out 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.
