The Carlo Gavazzi RK Series solid state relays consists of 2-pole solid state relays contained in one housing with the possibility to control each pole independently (RKD2. models) or both poles together (RK2. models). Ratings for both versions go up to 600 VAC, 75 AAC per pole. The RK.C models have control termination through a 2.54mm pitch connector. Terminated cables to mate with the RK.C are available and have to be ordered separately. The RK.P models have control termination with a 5.08mm pitch plug connector. In this case, the control plug is shipped with the solid state relay.
