Outputs (Receiver)

Both outputs OSSD1 and OSSD2 (OSSD = Output Signal

Switching Device) are control reliable, actively monitored PNP solid

state outputs. The outputs can carry a maximum of 0.5 Amps and

are short circuit protected. If the protected field is clear, the two

outputs are HIGH (active).

• An additional supply voltage must not be applied to the outputs.

RS-485 Communication Interface

This interface serves to communicate with the 440L-M8100

(optional). If the 440L-M8100 is not used, the connection is not

used.

ATTENTION: Both output signals must

be processed separately. They must not be

connected in series or parallel.
