The ABB CT-AHS.22S is an off-delay time relay with auxiliary voltage input, manufactured by ABB Stotz-Kontakt GmbH in Germany. It is designed for use in industrial and marine automation control panels where a timed delayed de-energisation of output circuits is required after the control voltage is removed. Onboard vessels, this type of relay is commonly found in machinery automation panels, pump control systems, and switchgear assemblies where sequenced shutdowns are critical to safe and reliable operation.
Key Features
✓ Off-delay timing function with auxiliary voltage input, allowing the timing circuit to operate independently of the load control voltage
✓ Wide supply voltage range — AC 24–240V at 50/60Hz and DC 24–48V — compatible with varied shipboard panel configurations
✓ Time range of 0.05 seconds to 300 hours, providing broad flexibility across automation and control sequencing requirements
✓ 2 changeover (C/O) output contacts rated AC15: 230V 3A and DC13: 24V 2A, suitable for direct integration into relay logic circuits
✓ Manufactured in Germany by ABB Stotz-Kontakt GmbH to ABB’s established industrial quality standards
Marine Applications
Machinery room automation panels requiring timed shutdown sequences following loss or removal of control voltage
Pump and compressor control circuits where delayed stop functions prevent water hammer or mechanical stress on startup and shutdown cycles
Engine room ventilation and HVAC systems requiring timed relay outputs for sequential fan or damper control
Alarm, monitoring, and fault annunciation panels where timed output suppression or delayed activation is required
General relay logic in engine control rooms, cargo automation systems, and electrical switchgear panels across vessel types
Why Marine Engineers Choose
The ABB CT-AHS.22S is a well-regarded timing relay in marine and industrial automation environments, valued for its broad AC and DC voltage compatibility, reliable changeover contacts, and the precision timing range that ABB Stotz-Kontakt GmbH components are known for — simplifying panel design and reducing the risk of timing-related faults in critical shipboard systems.
Ideal For
General cargo vessels, tankers, bulk carriers, container ships, offshore support vessels, ferries, cruise ships, and industrial marine installations requiring dependable off-delay timing relay solutions in automation, control, and switchgear panels.
