16 channels relay modules relay control panels, with optocoupler protection with LM2596 power
16-way relay module relay PLC control board optocoupler isolation LM2596 power supply 5v12v24v optional
1. Relay contact capacity 10A 250V, with optocoupler protection. The onboard power module does not require external power. I / O port driving active low.
2, can be used as a microcontroller development board module, can be used as home appliance control, can also be used as PLC expansion output.
1. Control signal voltage range: the trigger signal is low level.
2. Strong anti-interference ability and stable performance;
3. All 1-16 channels can be turned on / off at will, or any channels.
4. Output form: directly connected to AC 220V 10A or DC30V 10A load.
5. The COM terminal of each relay is independent, which is 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, which is on and off.
7. The interface design is user-friendly. All interfaces can be directly led out through the terminal block, which is very convenient.
8. There are 4 fixing bolt holes for easy installation.
9. PCB board size: 180MM (L) * 90MM (W) * 20MM (H).
Supply voltage: 5V 12V 24v (DC)
Supply current: greater than 200mA-500mA
Each relay can load: 250V 10A (AC) or 30V 10A (DC)
1. The power supply must meet the scope of use, DC 5V 12V 24V;
2. The power supply must be connected in accordance with the wiring diagram.
3. The product using the LM2596S step-down chip has a slight fever, which is normal, and the relay has a normal fever for a long time, which is normal.
4. Load power must leave a certain margin for the relay load, and should avoid high power (about 2000W) and long-term working environment, which will have a certain impact on the product life.
