The ABB CT-AHS.22S is an off-delay time relay with auxiliary voltage supply, manufactured by ABB STOTZ-KONTAKT in Germany under part number 1SVR730110R3300. Designed for industrial and marine control panel applications, it provides precise time-delay switching for shutdown and de-energisation sequences across a wide range of control voltages. Onboard vessels, time relays of this type are found in engine room automation systems, switchboard panels, alarm circuits, and auxiliary machinery control — wherever a controlled, reliable delay between a trigger event and circuit deactivation is required.
Key Features
✓ Off-delay timing function with auxiliary voltage supply — enables controlled deactivation after a trigger signal is removed
✓ Wide timing range: 0.05 seconds to 300 hours — adaptable to a broad spectrum of marine automation requirements
✓ Dual voltage input: AC 24–240V 50/60Hz and DC 24–48V — compatible with diverse shipboard power supply configurations
✓ 2 changeover (C/O) contacts rated at 4A — suitable for switching control signals and monitoring circuits in panel environments
✓ Manufactured in Germany by ABB STOTZ-KONTAKT — industrial-grade construction from a globally recognised automation brand
Marine Applications
Engine room automation panels requiring time-delayed deactivation sequences for machinery shutdown and run-on procedures
Auxiliary machinery control — cooling pumps, fans, compressors, and HVAC units with timed run-on or delay-off functions
Alarm and monitoring circuits where a controlled delay is required before signal activation or system reset
Switchboard and distribution panel automation on merchant vessels, offshore platforms, and naval vessels
Safety and protective relay schemes including bilge pump control, fire detection ancillaries, and general-purpose automation circuits
Why Marine Engineers Choose ABB CT-AHS.22S
ABB time relays are specified across marine automation systems worldwide for their broad voltage compatibility, consistent timing accuracy, and long service life. The CT-AHS.22S covers an exceptionally wide timing and voltage input range, reducing the need for multiple relay variants across a vessel’s control panels — making it a practical choice for both original equipment builds and retrofit projects.
Ideal For
Merchant vessels, offshore supply vessels, tankers, bulk carriers, cruise ships, naval vessels, offshore platforms, and industrial marine installations requiring reliable time-delay relay solutions within automation and switchboard control systems.
