The ABB CT-ERS.12 is an on-delay time relay from ABB Stotz-Kontakt, manufactured in Germany. It introduces a configurable time delay before activating its output contact — a function critical in machinery start sequences, alarm inhibit circuits, and sequential control logic aboard vessels. With a wide AC/DC input range and an adjustable delay spanning 0.05 seconds to 300 hours, this relay suits the demanding operating conditions found in ship automation panels, engine room control systems, and auxiliary machinery control within the broader industrial and marine control category.
Key Features
✓ On-delay timing function with a range of 0.05 seconds to 300 hours, covering sequencing and delay requirements across a wide variety of control applications
✓ Wide input voltage compatibility: AC 24–240V (50/60 Hz) and DC 24–48V on terminals A1–A2, accommodating diverse vessel power supply configurations
✓ Single changeover (1 C/O) output contact rated at 4A, with AC15 230V 3A and DC13 24V 2A switching performance for both AC and DC load circuits
✓ High impulse withstand voltage (ULMP: 4KV) and fast-acting fuse protection at 10A, providing robust circuit protection in electrically demanding environments
✓ ABB Stotz-Kontakt manufacture, made in Germany — a brand recognised for precision and reliability in continuous-duty industrial and marine automation systems
Marine Applications
Engine room alarm and start inhibit circuits requiring a configurable hold-off delay before triggering alerts or enabling downstream control actions
Auxiliary machinery sequencing — controlling pump, fan, or compressor start intervals to prevent simultaneous load surges on vessel power distribution systems
Automation panel timer functions in shipboard control systems for ballast, HVAC, fire detection, and power management applications
Bridge and cargo control console relay timing logic where precise, repeatable delays are required within DIN-rail mounted panel assemblies
Retrofit and direct replacement of existing ABB CT-ERS series time relays in shipboard control panels, minimising downtime during maintenance or upgrade work
Why Marine Engineers Choose
The ABB CT-ERS.12 is a compact, well-established time relay with a broad input voltage range, long-span timing adjustment, and the build quality associated with ABB Stotz-Kontakt — making it a dependable choice for critical sequencing and delay functions in shipboard control panels where consistency and precision are essential.
Ideal For
Merchant vessels, offshore platforms, naval auxiliaries, cruise ships, tankers, bulk carriers, and industrial marine installations requiring DIN-rail mounted on-delay time relay solutions in automation and control panel assemblies.
