CR-M3SS ABB Plug-in control relay module Spring terminal Double conversion contact
CR-M3SS ABB Plug-in control relay module Spring terminal Double conversion contact
ABB CR-M3SS is a high-performance plug-in control relay module in the ABB CR-M series, specifically designed for industrial automation, process control and OEM equipment that requires a medium number of contacts and high installation efficiency. This product adopts the Spring Clamp technology and supports tool-free rapid wiring, significantly enhancing the assembly and maintenance speed. Equipped with 3 sets of conversion contacts (3CO), it can simultaneously achieve multi-channel signal switching, status feedback and interlock control. As a universal contact module, the CR-M3SS must be used in conjunction with the CR-PSS series sockets. The coil voltage is determined by the selected socket, achieving highly flexible system integration.
