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.
