9. Assignment of output relay and input terminal
* Current capacity available from DC 24V (Pin 1 and 2, 12) is max. 100mA in total.
* Since the Photocoupler is bi-directional, both interfaces, i.e. NPN (sink) and PNP (sourcing), are available
depending on the connection of COM.
* When connecting with NPN output, add the wire between No. 2 (+24V) and No. 3 (IN COM). See the left
figure below.
When connecting with PNP output, add the wire between No. 3 (IN COM) and No. 12 (24V return). See the
right figure below.
* Terminal block: Main unit: 163391000,
Wire connector: 1606740000, 1640030000 (manufactured by Weidmuller), one each used
