ABB CT-ERD.12 ON-delay time relay (order code 1SVR500100R0000) from the CT‑D family provides a single Form C (SPDT) output for delayed switching of a load. It accepts a control supply of 24–240 VAC or 24–48 VDC and offers a timing range from 0.05 seconds up to 100 hours, enabling precise delayed energization of connected circuits. Designed for automation and building control, CT-ERD.12 is used to trigger loads after a programmable delay via its one-changeover contact, making it a compact, reliable choice for time-based control tasks.
