Allen-Bradley 700DC-PK620Z24 PK Control Relay

Allen-Bradley 700DC-PK620Z24 PK Control Relay is a 24 VDC coil open-type control relay in the PK/700-P family. This PK-series device is designed to be paired with Allen-Bradley PK master contact cartridges to tailor the relay's contact configuration in industrial panels. Energizing the 24-volt DC coil actuates the installed PK contact cartridge, providing a compact, modular solution for switching control circuits in automation, interlock, and sequencing applications. The PK platform supports field-reconfigurable contact arrangements by selecting compatible PK cartridge options and mounting bases, enabling configuration without replacing the entire relay. Common uses include small- to medium-load control tasks in machine controls, process control logic, and safety-related interlocks where a reliable, plug-in relay is advantageous. The 700DC-PK620Z24 part number places this relay within Allen-Bradley's 700-Series PK family, designed for integration with standard 700-PK sockets and rails in control cabinets. This combination delivers straightforward maintenance and scalable expansion when building or updating control architectures in manufacturing environments.
