Maximum current sink/source = 50 mA.
Internally protected by electronic fuses.
A working bar in good operating condition will thus internally connect both outputs
to >20 V. Signalling becomes valid 5 seconds after power is applied.
Caution!
Voltage applied to the outputs must not exceed 28 V DC and must be of the correct
polarity.
The remote monitor signals are valid 5 seconds after power is applied, according to
the following conditions:
Remote Monitor outputs (OK, Status)
Both outputs are compatible with IEC 61131-2 Type 1, Type 2 and Type 3 PLC
inputs, capable of sinking or sourcing 50 mA continuously. The outputs can also be
used for direct driving of external lamps or relays. See wiring diagram and examples
in the next section.
