Max Current: 190mA
Trigger Current: 3-5mA
Low Level Trigger Current: 0-1.5V
High Level Trigger Current: 3-5V
Input Interface:
1. DC+: 5V positive power supply
2. DC-: 5V negative power supply
3. IN: corresponding with trigger signal level of relay
Output Interface:
1. NO: normally open interface
2. COM: common interface
3. NC: normally close interface
Trigger Mode Configuration:
The module has a trigger level selection terminal, each relay trigger level can be individually controlled, through the short-circuit cap to control. COM side is common, in the middle;
When the LOW (L) terminal is connected to the common terminal, it is a low level trigger; when the HIGH (H) terminal is connected to the common terminal, it is a high level trigger.
Normally Open Interface Work Mode:
COM port connect with loaded AC live line or DC positive power supply, NO port connects with loaded AC zero line or DC negative power supply, the load circuit is disconnected, when there is trigger signal iniput, relay pick up, and circuit connected, load work.
Normally Close Interface Work Mode:
COM port connect with loaded AC live line or DC positive power supply, NC port connects with loaded AC zero line or DC negative power supply, the load circuit is close, and load work normally. When there is trigger signal iniput, relay disconnect, and load is off work. Package Include:
1pcs 5V 4 Channel High/Low Trigger Relay Module
