Sensors according to EN 60947-5-6 (NAMUR)

or potential-free contacts can be connected to

the IMX12-DI03-1S-1NAM1R-PR/24VDC/CC

NAMUR repeater. The device is equipped with

an intrinsically safe input circuit and can be installed in zone 2. The output circuit is additionally equipped with 1 relay output. 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.

Thus, input circuit monitoring and the direction

of action can be switched separately. 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 spring

type terminals.
