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.<br/>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).<br/>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.<br/>4. Robust ABS Enclosure: Housed in sturdy ABS plastic casing, the relay is designed for harsh industrial conditions. Its robust structure ensures protect against dust, extending the product's lifespan.<br/>5. Versatile Automation Control: For RTU protocol, this relay module allows seamless integration with PC or PLC systems. It enables accurate control over external devices like motors, lights, and valves for enhanced automation.<p><br/></p><p><b>Specification:</b></p>Item Type: Relay Module<br/>Material: ABS<br/>Power Supply Method: 5.08mm Screw Terminal<br/>Hardware Interface: DB9 Male<br/>Control Interface: for RS232 Interface<br/>Communicating Protocol: for RTU Protocol<br/>Operating Time (5v): ≤10ms<br/>Release Time (5v): ≤5ms<br/>Maximum Switching Current: NO: 10A, NC: 5A<br/>Maximum Switching Power: NO: 2770VA 280W, NC: 1250VA<br/><p><br/></p><p><b>Package List:</b></p><p>1 x Relay Module</p></div>:<p><br/><br/><br/><br/><br/><br/><br/><br/><br/>:<span style="color: var(--w-e-textarea-color);"><br/></span></p></div></div></div>
