Welcome to customize the circuit board you need.
- Voltage range of control signal: the trigger signal is 0-2v at low level;
the voltage at high level shall not exceed 5V.
- Adopt industry quality isolation optocoupler, strong anti-interference ability, stable
performance; trigger current only needs 3mA.
- All 1-16 channels can be opened / closed, or any channel.
- Output form: directly connected to AC 220V 10A or dc30v 10A load.
- Each relay common terminal com is independent which is convenient for users to
access different signals. Each relay has normally closed and normally open ports.
- Each relay is equipped with an action indicator light, which is on when it is turned
on and off when it is turned off.
- The interface design is humanized. All interfaces can be directly connected through
the terminal block, which is very convenient.
- There are 4 fixing bolt holes for easy installation.
Power supply voltage: 5V 12V (DC)
Power supply current: more than 200mA
Load of each relay: 250V 10A (AC) or 30V 10A (DC)
- 12V relay contact capacity 10A 250V, with optocoupler protection. On board power
module does not need external power supply. I / O port drive low level is effective.
- It can be used as the development board module of single-chip microcomputer, the
writer’s electric control, and the PLC extended output
The power supply shall meet the use range, DC 12V;
The power supply shall be in accordance with the wiring diagram and shall not be
The product uses Im2596s step-down chip to slightly heat,which is a normal
phenomenon. The relay works for a long time, which is also a normal phenomenon;
