+20 V supply: 50 mA maximum
current output to drive other devices.
COM terminal is internally connected to 24G. When
multiple CP-8511s or other devices are powered
by a common source, uniform wiring polarity must
be maintained between all 24H and 24G terminals.
Check to ensure that the controller’s COM terminal
is not connected to any other ground reference.
