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

or potential-free contacts can be connected to

the 4-channel IM1-451-T isolating switching

amplifier.

The output circuits each feature a potential-free and short-circuit proof transistor and

the device also has a common alarm output.

Via eight switches on the front, the output

mode (work or quiescent current behavior, i.e.

NO/NC) can be switched on and off separately for each channel as well as wire-break (WB)

and short-circuit monitoring (SC).

When using mechanical contacts, wire-break

and short-circuit monitoring must be switched

off or the contacts must be wired with resistors

(II) (see circuit diagram).

The Pwr LED lights green to indicate operational readiness. The 2-color LED 1 lights yellow to indicate the switching status of the output. In the event of an input circuit error, the 2-

color LED turns red, with the input circuit monitoring switched on. Thereupon the output and

the alarm transistor are blocked.
