Overview

The ABB CT-MFC.21 multifunctional time relay (SKU: 1SVR508020R1100) delivers precise timing control for industrial automation with a 12-240V AC/DC supply range. This relay features 2 changeover (SPDT) contacts and supports 10 timing functions including ON-delay, OFF-delay, interval, pulse forming, and star-delta change-over modes. The 0.05s to 100-hour adjustable time range covers short delays and extended process cycles, making it suitable for machinery sequencing, conveyor control, and process automation. Designed for DIN-rail mounting, the CT-MFC.21 integrates easily into control panels with compact dimensions of 17.5mm width, 80mm height, and 63mm depth. Its voltage-independent triggering ensures reliable operation across global power systems without requiring additional power supplies. The relay’s robust construction meets industrial standards for vibration, temperature (-20°C to +60°C operation), and electrical noise immunity. Common applications include motor start delay circuits, pump control systems, lighting sequences, and safety interlock timing in manufacturing, water treatment, and HVAC systems. The 2 changeover contacts allow flexible switching configurations for controlling multiple loads or signaling states. With ABB’s industrial-grade reliability, this relay minimizes downtime in critical control applications while providing accurate timing repeatability.
