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

or potential-free contacts can be connected to

the IMX12-DI01-2S-2R-0/24VDC/CC isolating

switching amplifier. The device is equipped

with intrinsically safe input circuits and can

be installed in zone 2. A DIP switch allows

toggling of the device 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.
