22. Connector allocation
Data devices use 10-pin terminals as their input/output interfaces. Pin allocation is as follows:
Note
：
--GND: Ground
--VCC: DC9—30V power input, operating current: 350mA
--DATA-: communication interface (RS232: data receiving; RS485: RS485-)
--DATA+: communication interface (RS232: data sending; RS485: RS485+)
--INIT: Reset
--IN.COM: 5-24 negative voltage common input end
--IN0
、
IN1
、
IN2
、
IN3: 5-24V positive voltage input
--NO1
、
NO2
、
NO3
、
NO4: relay normally open end
--NC1
、
NC2: relay normally closed end
--COM1
