Industrial Relay Module For RS232 Interface RTU Optocoupler Isolation Modul HEN.
Feature: \n 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.\n2. 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).\n3. 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.\n4. 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.\n5. Versatile Automation Control: For RTU protocol, this rela:
