1SVR508100R0100 ABB CT-ERC.22 Time Relay ON-delay 2c/o
ABB CT-ERC.22 electronic ON-delay time relay with two changeover outputs, 24–48 V DC or 24–240 V AC control supply and seven selectable time ranges from 0.05 s to 100 h.
The ABB CT-ERC.22 is a compact and reliable electronic ON-delay time relay designed for precise timing and sequencing in industrial control and automation systems. As part of the established ABB CT-C timer relay range, it provides dependable delay-on-make operation for control panels, machinery and electrical automation applications.
This single-function timer relay provides seven selectable time ranges covering 0.05 s to 100 h, allowing the required delay to be set accurately for a wide range of control applications. Its front-mounted adjustment controls and LED status indication simplify commissioning, operation and troubleshooting.
With a rated control supply voltage of 24–48 V DC or 24–240 V AC and two changeover relay outputs, the CT-ERC.22 provides flexible switching capability for industrial control circuits. Its compact 17.5 mm wide housing is well suited to installations where control panel space is limited.

Reliable Timing for Industrial Automation
Time relays such as the ABB CT-ERC.22 provide controlled delays within electrical automation systems. The ON-delay function introduces a defined delay after the control signal is applied before the relay outputs change state, helping coordinate contactors, motors, valves, indicators and other control equipment.
The CT-C range is designed for practical industrial control applications where accurate and repeatable timing is required. The CT-ERC.22 combines selectable time ranges, adjustable delay settings and clearly visible status indication in a compact housing suitable for control cabinets and electrical distribution equipment.
Typical Applications
Industrial automation and control panels.
Motor and contactor sequencing systems.
Machine control and production equipment.
Delayed switching of valves and actuators.
Lighting and signalling control systems.
Process control and electrical sequencing applications.
