Feature:
1. Functionality: A relay is an electrical control device, which causes the controlled quantity in the electrical output circuit to have a predetermined step change when the change in the input quantity (excitation amount) meets the specified requirement.
2. Interactive System: It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit).
3. Automation Ready: Usually used in automated control circuits, it is essentially an automatic switch that uses a small current to control the operating of a large current. Therefore, it plays roles such as automatic adjustment, safety guard, and circuit conversion in the circuit.
4. 8 Bit MCU: The RS232 relay module is designed with a stable 8 bit MCU, complemented by an RS232 level communicating chip, optimizing the performance and reliability of communicating and control systems.
5. 1 Channel Relay Module: Using the standard RTU format of RS232 communicating protocol, it can realize 1 channel input signal detection and 1 channel relay output, which can be used in digital quantity detection or power control occasions.
