Allen-Bradley 700-PT Pneumatic Time Delay Relay

Allen-Bradley 700-PT Pneumatic Time Delay Relay is a pneumatic timing unit designed to mount on Bulletin 700-P or PK relays (and on 2-pole Bulletin 700-PH relays) to add a precise on-delay timing function to relay circuits. It provides a timing range of 0.1 to 60.0 seconds and carries a 10 A contact rating for the timed contacts, making it suitable for control panel applications that demand a solid, mechanical delay without electronics. This open-type timing accessory integrates with the 700-P family to deliver controlled delays in relay-driven circuits, with pneumatic actuation ensuring predictable timing independent of electrical coil conditions. Use cases include scenarios where a load or coil must energize after a set interval or release after a defined delay, enabling simple sequencing and interlocking in automation systems. By combining the 700-PT with Bulletin 700-P or PK relays, technicians can realize compact, field-installable timing solutions within existing control architectures, without needing separate timer modules or complex wiring.
