The ABB CT-ERS.22S is a DIN-rail mounted on-delay time relay from ABB’s STOTZ-KONTAKT range, engineered for precise timing control in industrial and marine automation applications. With a broad supply voltage acceptance across both AC and DC inputs and a timing range spanning 0.05 seconds to 300 hours, it is well suited to sequential control, motor start delay, and alarm logic in shipboard control panels and auxiliary machinery automation systems.
Key Features
✓ Wide supply voltage compatibility: AC 24–240V (50/60 Hz) and DC 24–48V for flexible panel integration
✓ Extended timing range of 0.05 seconds to 300 hours covering a broad spectrum of delay requirements
✓ Dual changeover (2 C/O) output contacts with 4A thermal current rating for reliable load switching
✓ High impulse withstand voltage of 4 kV and fast-blow fuse protection rated at 10A
✓ Certified to IEC/EN 61812-1 and IEC/EN 60947-5-1; manufactured in Germany to ABB quality standards
Marine Applications
Sequential start delay control for pumps, motors, and compressors in engine rooms and machinery spaces
Alarm and monitoring panel timing logic for vessel safety and management systems
HVAC and ventilation system control requiring timed switching sequences
Ballast, bilge, and cargo handling panel automation circuits
Auxiliary machinery interlocking and control system timing in bridge and automation panels
Why Marine Engineers Choose ABB CT-ERS.22S
The ABB CT-ERS.22S combines a wide input voltage range, an extended timing span, and dual changeover contacts in a compact DIN-rail form factor — making it a dependable and adaptable solution for timing-critical marine control applications where certification to recognised international standards is required.
