Outputs (Receiver)
The output voltage U
A
of each channel depends on the supply
voltage U
V
and the switched load and is at least
U
A
= U
V
- 2V
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.
