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.
