The relay coupler, also known as coupling relay, relay module, or interface relay, with the OEM part number 228565 from Polar, is an electrical relay for signal processing and load switching in electrical control and automation systems. It has the dimensions 10 x 10 x 5 cm and weighs 0.05 kg. Relay couplers function as an interface between control levels and power circuits, provide galvanic isolation, and amplify weak control signals. This enables the safe control of loads such as motors, valves, or lighting systems. Typical applications are found in mechanical engineering, process automation, and control cabinet construction for reliable and safe switching of various loads.
