Time Delay Relays

Marine Time Delay Relays & Intelligent Power Management Controls for Boat Builders, Marine Electricians & OEMs

Technical Marine Supplies supplies a specialist range of marine time delay relays and intelligent power control devices designed to improve battery protection, automate electrical systems and enhance operational reliability aboard sailing yachts, motor vessels, commercial craft and specialist vehicles. Our range includes EGIS PT Series and TDR Series time delay relays, engineered for demanding marine and mobile power applications.

Time delay relays are widely used to automatically control electrical loads, preventing battery drain and ensuring critical systems remain operational when needed. By delivering power for a predefined period or disconnecting circuits after a programmed delay, these devices help maximise battery life, reduce maintenance requirements and improve overall system efficiency. They are particularly valuable for onboard electronics, communications equipment, monitoring systems and auxiliary electrical loads.

Designed for harsh operating environments, EGIS time delay relays feature sealed construction, ultra-low standby current draw, integrated thermal overload protection and adjustable shutdown timing. Additional features such as under-voltage and over-voltage protection help safeguard sensitive onboard electronics, while diagnostic LED indicators simplify system monitoring and troubleshooting. Delay periods can be adjusted from 15 minutes up to 8 hours, providing flexibility across a wide variety of vessel and vehicle installations.

As a specialist B2B marine distributor, Technical Marine Supplies supports boat builders, marine electricians, vessel integrators, commercial operators and OEM manufacturers with expert technical advice and dependable supply. Whether you're specifying electrical controls for a new-build vessel, upgrading battery management systems or integrating automated power control into a commercial project, our team can help identify the right solution.
