Why Choose the ABB CT-ERS.22P ON-Delay Timer?
The ABB CT-ERS.22P is a reliable electronic ON-delay timer relay designed for precise time-delayed switching in industrial automation, control panels and electrical control systems. As part of the proven ABB CT-S timer range, it provides a dedicated ON-delay function with selectable timing ranges and two changeover relay contacts for flexible control applications.
The CT-ERS.22P provides 10 selectable time ranges from 0.05 s to 300 h, allowing accurate timing control across a wide variety of industrial applications. Front-face operating controls provide straightforward adjustment, while the Easy Connect push-in terminals enable simple electrical installation.
With a rated control supply voltage of 24–240 V AC / 24–48 V DC and 2 c/o (SPDT) relay contacts, the CT-ERS.22P is suitable for machinery, automation and electrical control circuits where a controlled delay is required before the output contacts change state. Its compact 22.5 mm housing is designed for DIN-rail mounting within control cabinets.

Reliable Time-Delayed Control for Industrial Automation
ON-delay timer relays such as the ABB CT-ERS.22P provide controlled switching after a defined time period has elapsed. This makes them useful for sequencing, interlocking and delayed operation within industrial machinery and electrical control systems.
The CT-ERS.22P combines a dedicated ON-delay function with ten selectable time ranges, allowing the same timer relay to accommodate applications ranging from short switching delays through to extended timing periods. Its two changeover relay outputs provide flexible switching, while the compact DIN-rail design supports straightforward installation in control cabinets.
Typical Applications
- Industrial automation and control panels.
- Delayed starting and sequencing circuits.
- Machine control and production equipment.
- Motor and actuator control systems.
- Electrical interlocking and timing circuits.
- Lighting and building control systems.
- OEM machinery and industrial automation equipment.
