2 Channel 5V/12V/24V Relay Module
Model: YZQ-R002
Module Description
1.Normally open interface maximum load limit: AC 250V/10A, true DC 30V/10A
2. It uses patch optocoupler isolation, with strong driving ability and stable performance; trigger current
5mA;
3. The module operating voltage is 5V12V24V
4. The module can be set to high or low level trigger through jumpers 5. Fault-tolerant design, even if the control line is broken, the relay will not work;
6. Power indicator light (green), relay status indicator light (red) 7. The interface design is user-friendly, all interfaces can be directly connected through the terminal block
lead out, very convenient
8. There are 4 fixing bolt holes
Model: YZQ-R002
How to use
(1) Module interface:
1. DC+: Connect to the positive pole of the power supply (voltage is 5V, 12V, 24 according to the relay requirements)
2. DC-: Connect to the negative pole of the power supply
3. IN1: 1-way signal trigger terminal, which can be set to high or low level to control the relay to be attracted
4. IN2: 2-way signal trigger terminal, which can be set to high or low level to control the relay to be attracted
(2) Relay output terminal
1. NO: Relay normally open interface, suspended before the relay is attracted, and short-circuited with COM after attraction
2. COM: Relay common interface
3. NC1: 1-way relay normally closed interface, short-circuited with COM1 before the relay is attracted, and suspended after attraction
4. NO2: 2-way relay normally open interface, suspended before the relay is energized, short-circuited with COM2 after energization
(3) High and low level trigger selection terminal
1. S1 is the high and low level trigger selection for 1-way relay
2. S2 is the high and low level trigger selection for 2-way relay
