RK 2-pole solid state relays Benefits Space savings. The RK series consists of two solid state relays contained in one housing having a product width of 45mm. Fast installation. The RK solid state relay is ready for mounting to panel chassis or heatsink as the backplate is equipped with a pre-attached thermal interface. Easy wiring. The RK..P models are equipped with a pluggable spring terminal for easy and fast wiring of control connections. Low equipment downtime. The output of each pole is Description protected against over-voltages with an integrated transil. Long lifetime. Wire bonding technology reduces thermal and mechanical stresses of the output chips allowing a The RK series consists of 2-pole solid state relays larger number of operational cycles compared to other contained in one housing with the possibility to assembly technologies. control each pole independently (RKD2.. models) User friendly. LED indication per pole for visual or both poles together (RK2.. models). Ratings for indication of control status. both versions go up to 600 VAC, 75 AAC per pole. Food & Beverage certification conformance. The RK The RK..C models have control termination is certified for 100,000 cycle endurance test according through a 2.54mm pitch connector. Terminated to UL508. 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. Applications Plastic extrusion machines, thermoforming machines, blow moulding machines, coffee machines, electrical ovens, vending machines, soldering ovens, dryers, climatic chambers, air handling units, plastic sealing machines, shrink tunnels, etc. Main functions 2-pole AC solid state relay with either independent control for each pole or common control.
