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

or potential-free contacts can be connected

to the IM12-DI01-2S-2T-PR/24VDC/CC isolating switching amplifier. 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 potential-free transistors with a high cut-off frequency (10 kHz). 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 transistor of the associated output circuit then

locks 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.
