Feature:
1. High Performance: The relay module is designed to offer an enhanced relay experience with 4 channel functionality and includes an optocoupler for increased safety and efficiency.
2. Versatile Application: Ideal for use in various types of automatic control circuits. The relay module switch has the ability to make a pre set step change in the controlled variable when the change in the input quantity reaches a certain requirement.
3. Interactive Relationship: Boasting an impressive interactive relationship between the control system (input circuit) and the controlled system (output circuit), the relay module board is a practical automatic switch used to control the operating of large currents with a small current.
4. Enhanced Safety: The 4 channel relay module ensures safety guard, automatic adjustment and switching circuit, offering reliable functionality in protecting your equipment.
5. Practical Use: With the support for Modbus RTU Protocol, the 4 channel relay module switch can achieve the of 4 channel input signal detection, 4 channel relay output, and is applicable for digital quantity detection or power control occasions.
