5. Digital Input and Output Interfaces

5.1 Digital Inputs

QC400 contains an extended wiring IO board, which is powered by an independent
external 24V power supply. It has 34 ordinary inputs and 27 ordinary outputs (6 relays are
included). Effective input level can be determined to high or low according to the level
configuration of common terminal.

5.1.1 Input Interface Definition and Pin Functions

 INPUTCOM(input common terminal): an external 24V or 12V power supplied.
 Digital input interface uses a 37-pin DB terminal and 20-pin socket, which contains the
power and common wiring ports.
Pins' arrangement of digital input port is shown as following:
Note:
Input board contains three INPUTCOM ports. All input ports can be used if only one of
INPUTCOMs is supplied with 24V.
