Sensors according to EN 60947-5-6 (NAMUR)
or potential-free contacts can be connected
to the IMX12-DI03-1S-2T-S/24VDC 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 potential-free transistors. 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. Then, the
transistor of the corresponding output circuit
locks.

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.
