The DOT On-Delay Timer Relay, developed by Borna Electronics, is one of the most widely used control circuit devices in industrial electrical panels. The relay is designed to introduce a controlled delay between power application and output activation, making it ideal for sequencing operations, motor control circuits, and automation systems.
Borna Electronics offers the DOT timer in a wide range of timing ranges and supply voltages, providing flexibility for diverse industrial applications. The adjustable timing setting allows users to precisely configure the required delay period.
