16 Channel 5V Relay Module w/Optocoupler Isolation Expansion Board Module
16 Channel 5V Relay Module with Optocoupler Isolation Protection Expansion Board Module for SCM PLC
1. The control signal voltage range is the trigger signal low level 0-2V, and the high level voltage can not exceed 5V.
2. The isolation optocoupler with the highest quality in the industry has strong anti-interference ability and stable performance, and the triggering current only needs 3 mA.
3. The 1-16 way can be opened or closed at any time, or any road.
4. Output form: load directly connected to AC 220V 10A or DC30V 10A.
5. Each relay common terminal COM is independent, convenient for users to access different signals, each relay with normally closed and normally open ports.
6. Each relay is equipped with an action indicating lamp, which is light on when absorbed, and light out when disconnected.
7. The interface design is humanized, and all the interfaces can be directly connected by wiring terminals, which is very convenient.
8. Equipped with 4 fixed bolt holes for easy installation.
1. Relay contact capacity 10A 250V, with optocoupler protection.
2. The external power supply module does not need external power supply. I/O port driver is low level effective.
3. It can be used as MCU development board module, which can be used for home appliances control, and can also be used for PLC extended output.
Supply voltage: 5V 12V 24V (DC)
Power supply current: greater than 200mA
Each relay can load: 250V 10A (AC) or 30V 10A (DC).
1. The power supply should meet the application scope and DC 5V 12V 24V;
2. The power supply must not be reversed according to the wiring diagram.
3. The product uses LM2596S buck chip to have the slight fever, belongs to the normal phenomenon, the relay long time work also has the normal fever phenomenon, belongs to the normal phenomenon;
4. Load power should leave a certain margin for the relay load, should avoid high-power (about 2000W) and long-term working environment, will have a certain impact on product life.
Please allow 1-3mm differs due to manual measurement.
Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understanding.
