ABB ghc4610104r004 Electronic Time Delay Relay

ABB ghc4610104r004 Electronic Time Delay Relay is a compact electronic timer from ABB's CT-E timer family that provides a single-function delay-on timer with a changeover output. The device uses a single changeover contact (SPDT) with common 15 and normally open 16/normally closed 18 terminals, with control input at A1-Y1 and supply on A1-A2/B1. Timing is initiated by the control input; when the input is opened the preset delay commences and, at the end of the selected interval, the output relays de-energize; the red LED lights to indicate the output is energized. The unit requires a continuous control supply for timing; minimum control pulse length is 20 ms. The product is used to sequence equipment in automation applications such as motor start-up sequencing, pumps, conveyors, lighting, and other controlled loads, including star-delta motor starting. ABB’s catalog notes that time relays of this family are designed for panel mounting and OEM equipment, offering robust timing performance in industrial environments. The ghc4610104r004 variant is marketed as a C461 delay-on timer model with ABB’s standard reliability, designed to function in control circuits where a timed action is required after a trigger is applied or released.
