I/O Terminal Connector - Pin Assignment
Pin Function Description
1 GND
Four sets of Digital Input, DI1 until DI4; the internal device is also
photo-coupled electrical relay. In practice, the external device can be
simply an On/Off switch. Four sets of On/Off switch can be connected as
different trigger source.
2 Digital input 4
3 Digital input 3
4 Digital input 2
5 Digital input 1
6 DO_NO Digital output implementation; Pin6 to COM (Pin7) is a Photo-coupled
relay on Normal Open status. External device can directly connect to the
terminals. However the current that will go through the 2 nodes must not
exceed 130mA. An external “Relay” can also be connected to the
terminals as an implementation. In this case, current (or/and voltage)
limitation is specified by the external Relay.
7 DO_COM
