Supply voltage: DC 12V
Trigger mode: High / low level trigger
Normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A
Trigger current 5mA
The power indicator (green); the relay status indicator (red)

Module Interface:
DC + : Power supply positive (module supply voltage must be DC, and the voltage to be consistent with the relay voltage.)
DC - : Power supply negative
IN1-IN8 : According to the setting of each way, it can control the corresponding relay to be high or low.

Relay output:
All interfaces can be directly connected,user-friendly
NO1 - NO8: relay normally open interface
COM1 - COM8: relay common interface
NC1 - NC8: normally closed relay interface

High / low trigger select :
S1-S8 is the relay 1-channel to 8-channel high / low trigger selection
COM and Low connected, the relay is low-level trigger
COM and High connected. the relay is high-level trigger

Pacakage included:
2 x 8 channel relay module
