ATC 305B101A10XX Electronic Timer Relay

ATC 305B101A10XX Electronic Timer Relay is a compact, integrated timer-relay device from Rockwell Automation that combines a timing function with a relay in a single enclosure. It is used in control panels to create precise time delays and timed sequences in automation systems; when the input trigger is received, the internal timer starts and the relay output changes state after the programmed interval, enabling or interrupting power to connected loads. The 305B101A10XX designation identifies the exact variant within the 305B family, a line of electronic timer relays used to coordinate sequencing in industrial equipment such as conveyors, motors, actuators, and indicator circuits. This timer-relay is designed for installation in standard control circuits alongside other ATC components, providing a simple, reliable means to implement delayed actions without requiring separate timer modules.
