Features: New and high quality. · 5V 16-channel relay interface board, each requires 15-25mA drive current. With a large current relay, AC250V 10A; DC30V 10A. ? Standard interface that can be directly controlled by a microcontroller (Arduino, 8051, AVR, PIC, PLC, DSP, ARM, ARM, MSP430, TTL logic). Indicates the LED relay output status. Size: 18 cm × 9 cm × 1.8 cm (5.47 in × 2.04 in × 0.67 in).
Application:
1. 12V relay contact capacity 10A 250V, with optocoupler protection. The onboard power module does not require an external power supply. I/O port driver low level effective.
2. Can be used as a microcontroller development board module, can be controlled by writer's electronics, or can be used as a PLC extension output.
Module features:
1. Control signal voltage range: Trigger signal is low-level 0-2V; The high-level voltage cannot exceed 5V.
2. Quality isolation optocoupler with strong anti-interference ability and stable performance; The triggering current only requires 3mA.
3. 1-16 channels can be turned on/off at will, or any channel.
4. Output form: Directly connected to AC 220V 10A or DC 30V 10A load.
5. Each relay's common COM is independent, making it convenient for users to access different signals. Each relay has normally closed and normally open ports.
6. Each relay is equipped with an action indicator light, which turns on when engaged and off when disconnected.
7. The interface design is user-friendly, and all interfaces can be directly connected and led out through wiring terminals, which is very convenient.
8. There are 4 fixed bolt holes for easy installation.
9. PCB board size: 180MM (L) * 90MM (W) * 20MM (H).
Electrical parameters:
Power supply voltage: 5V 12V (DC)
Power supply current: greater than 200mA
Each relay can load: 250V 10A (AC) or 30V 10A (DC)
Product Instructions:
1. The power supply should meet the usage range, with a DC voltage of 12V;
2. The power supply should follow the wiring diagram requirements and should not be connected in reverse;
3. The product uses the LM2596S voltage reducing chip, which slightly heats up, which is a normal phenomenon. The relay also has normal heating when working for a long time, which is a normal phenomenon;
4. The load power should leave a certain margin for the relay load, and avoid environments with high power (around 2000W) and long-term operation, which will have a certain impact on the product life.
