700-PKB40 | Allen-Bradley 2nd Level Adder Deck, 4 Pole, 20A Contact

The 700-PKB40 is a 2nd Level Adder Deck designed by Allen-Bradley to expand the contact capabilities of control relays. It features 4 poles and supports a 20-ampere contact rating, enabling switching of multiple circuits. This add-on component is commonly used in industrial control panels where additional relay outputs are needed. Its modular design ensures easy integration and configuration.

This adder deck provides four (4) poles, meaning it has four separate sets of contacts that can be wired independently. Each pole supports up to 20 amps, making the deck suitable for high-load or parallel circuit switching. This multi-pole design improves control flexibility in complex relay logic. Each pole operates mechanically in sync with the base relay.

The 700-PKB40 is compatible with Allen-Bradley control relays, particularly from the 700 series. It stacks or mounts onto the main relay assembly to expand contact functionality. Compatibility depends on the relay model and configuration, so reference the Rockwell Automation accessory matrix to confirm support. The design ensures seamless mechanical and electrical integration.

No, the adder deck connects mechanically and electrically to the base relay without additional internal wiring. However, each of the four contact outputs will require external wiring via the relay’s terminal blocks. Ensure wiring complies with 20A-rated conductors and secure tightening torque. Always follow Rockwell Automation’s wiring and safety standards.

While specific datasheet dimensions may vary slightly, typical Allen-Bradley 2nd level decks are around 75–85 mm in height, 45–55 mm in width, and 60 mm in depth, depending on relay type. The form factor is designed for easy integration in standard 700 series relay configurations. Always check the technical drawing for exact fit within your panel design.
