I/O terminals on OPTA5 (coded terminal painted black)
NOTE: Encoder inputs are wide range inputs that can be used with encoders using +15V or +24V.
Technical data:
NOTE: A high pulse frequency combined with a great cable capacitance places a considerable load
on the encoder. Apply therefore as low a voltage as possible for the encoder supply, rather lower
than 24V. The manufacturer also recommends to place jumper X4 to position +15V, if allowed in the
voltage range specification of the encoder.
