All outputs are electrically isolated from each other and from the power supply.
Digital outputs 41 / 42 and 51 / 52 are not electrically isolated from each
other. Terminals 42 / 52 have the same potential.
* Only in conjunction with additional ‘24 V DC loop power supply (blue)’ plug-in card in slot OC1.
