2. Trigger mode configuration description
The module has a trigger level selection terminal, each relay trigger level can be controlled individually, through the short-circuit cap for control. com is the public terminal, in the middle.
When the LOW (L) end and the public terminal is connected, for the low level trigger; when the HIGH (H) end and the public terminal is connected, for the high level trigger.

Module interface:
DC+: connected to the positive pole of the power supply
DC -: Connected to the negative electrode of the power supply
IIN1: 1 channel signal trigger terminal can be set high or low-level control relay suction
IN2: 2-way signal trigger terminal can be set high or low-level control relay pull
Relay output:
NO1: 1 relay normally opens the interface, the relay is suspended before suction and short-connected with COM1 after suction
COM1: 1 relay common interface
NC1: 1 relay normally closed interface, relay and COM1 short connect before closing, after closing suspended
NO2: 2 relay normally opens the interface, the relay is suspended before suction and short-connected with COM2 after suction
COM2: 2 relay common interface
NC2: 2-way relay normally closed interface, relay and COM2 short connect before closing, after closing suspended
