Product Description
Product Overview
The BROYCE B1DO is a Delay On Operate Timer Relay designed for industrial control applications. Manufactured by Broyce Control, a UK-based specialist in electrical and electronic components, this relay provides a time-delayed activation of its output upon receiving a power signal, making it suitable for sequencing, automation, and protection tasks in systems such as turbine controls, motor startups, or process machinery. The B1DO features a double-pole double-throw (DPDT) relay output and an 11-pin configuration, offering versatility for integration into various control panels. Although discontinued by Broyce Control, it remains relevant in legacy systems and replacement markets, with modern alternatives like the LEDO/2 suggested by the manufacturer.
