Why Choose the Carlo Gavazzi RKD2A23D50C Solid State Relay?
The Carlo Gavazzi RKD2A23D50C is a robust two-pole solid state relay (SSR) designed for reliable switching of two-phase AC loads in industrial automation, heating and electrical control applications. As part of the Carlo Gavazzi RK series, it uses zero-cross switching technology to help reduce electrical transients and electromagnetic interference when switching AC loads.
This panel-mounted solid state relay provides semiconductor switching without the mechanical contacts associated with conventional electromechanical relays. Its two-pole configuration provides independent control of each pole, while built-in overvoltage protection helps protect the semiconductor switching stage in demanding industrial environments.
With a rated operating current of 50 A per pole at AC-51 and an operating voltage range of 24–265 V AC, the RKD2A23D50C is suitable for a wide range of industrial AC loads. The relay uses a 4–32 V DC control input, zero-cross switching and connector-pin control termination, providing a practical interface for industrial automation systems.

Reliable Zero-Cross Switching for Industrial Loads
Solid state relays such as the Carlo Gavazzi RKD2A23D50C use semiconductor switching technology to control AC loads without mechanical contacts. The zero-cross switching function switches the load close to the AC voltage zero crossing, helping reduce electrical stress, switching transients and electromagnetic interference.
The RK series is designed for industrial automation, heating and electrical control applications where dependable solid state switching is required. The RKD2A23D50C combines two-pole switching, a 24–265 V AC operating range, built-in overvoltage protection and a low-voltage DC control input in a compact panel-mounted format. Its dual-control configuration allows the two poles to be controlled independently where required.
