Product Description

The 8MB12Z relay, part of the RKM series relay lineup, is a 4P2 contactor module designed for industrial control systems. It integrates 4 input channels and 2 high-capacity output relays, supporting direct connection to up to 8 auxiliary modules for expanded functionality. The module features an RS-485 interface with Modbus RTU protocol compatibility, operates within 12-48V DC, and functions reliably in temperatures from -20°C to 70°C. Ideal for automation, energy management, and machinery sectors, its compact design ensures space efficiency while maintaining robust performance. Key strengths include high switching endurance (100,000 cycles) and surge protection, though it lacks built-in display or battery backup. The contactor’s 10mm detection range ensures precise relay activation, suited for critical electrical load management in demanding environments.
