2 Channel High and Low Level Trigger Relay Module DIY Electronics Projects

Label:Yes The interface design is humanized. All interfaces can be directly connected through the terminal, which is very convenient. Fault-tolerant design, even if the control line is broken, the relay will not move. Using SMT optocoupler isolation, it has strong driving ability and stable performance; trigger current is 5mA. The module adopts premium relays with normal interface and maximum load: AC 250V/10A, DC 30V/10A. Modules can be triggered by setting high or low levels through wire jumper.Equipped with 4 fixed screw holes, easy to install.

Specification: Working voltage: 5V, 12V, 24V(Optional) Max load: AC 250V/10A; DC 30V/10A Channel: 2 Product dimension: 50*46*18.5mm(1.97*1.81*0.73in) Hole Diameter: 3.1mm(0.12in) Hole Spacing: 44.5*35.5mm(1.75*1.40in) Power light: Green Relay light: Red Board color: Red

Technical Specifications Relay Version: 5V Quiescent Current: 5mA Current: 190mA Trigger Current: 2-4mA Trigger Voltage (Low): 0-1.5V High: 2.5-5V Relay Version: 12V Quiescent Current: 5mA Current: 80mA Trigger Current: 2-4mA Trigger Voltage (Low): 0-4V High: 4.5-12V Relay Version: 24V Quiescent Current: 5mA Current: 50mA Trigger Current: 2-4mA Trigger Voltage (Low): 0-8V High: 8.5-24V

Package list: 1 * Relay Module

Note: Module interface: 1. DC+: Connect the positive pole of the power supply 2. DC-: Connect power supply negative pole 3. IN1:1 signal trigger terminal, can set high or low level control relay suction 4. IN2:2 signal trigger terminal, can set high or low level control relay suction

Relay output: 1. NO1: 1 channel relay usually opens the interface. The relay is suspended before suction and short-connected with COM1 after suction. 2. COM1: 1 channel relay common Interface 3. NC1: 1 channel relay normally closed interface, short connection with COM1 before relay suction, suspension after suction 4. NO2: 2 channel relay often opens interface. The relay is suspended before suction, and is short-connected with COM2 after suction. 5. COM2: 2 channel relay common interface 6. NC2: 2 channel relay normally closed interface, short Connection with COM2 before relay suction, suspension after suction.

High and low level trigger selector: 1. S1 is the trigger selection of high and low level1 channel relay. 2. S2 is the trigger selection of high and low level 2 channel relay. 3.com and low short connection, the corresponding relay is low-level trigger, com and high short connection is high-level trigger.
