Product Description:
The DG106A3 is a panel-mount electronic timer produced by Danaher within the Timers and Controllers series. It governs time-based switching sequences in automated machinery, allowing conveyors, heaters, or solenoids to energize or de-energize after a defined delay without relying on a PLC for simple timing functions. By combining a built-in power supply and change-over relay, the unit fits directly into control panels and supports repetitive operations where precise interval or delay execution is required.
The timer accepts a control source of 120 VAC (50/60 Hz) or 120 VDC, eliminating the need for additional converters in panels already wired for these levels. Users can choose between On-Delay and Interval operation, enabling either delayed energization or fixed-length pulse output from a single device. Its relay contacts are rated for 10 A at 120 VAC, so the timer can switch most fractional-horsepower motors or resistive loads directly. The internal relay is a DPDT configuration, providing two isolated change-over circuits for simultaneous control of independent loads. Mechanical installation is simplified by a standard rectangular panel opening of 92.0 x 44.0 mm, which matches many DIN front-panel cutouts.
Behind the bezel, the housing projects only 50.8 mm, conserving depth in shallow enclosures. The unit operates from 0 °C up to 60°C, covering typical factory ambient ranges without additional heating or cooling. It withstands mains dips lasting 20 ms without losing its timing cycle, reducing nuisance resets during brief power disturbances. Surge suppression withstands transients up to 600 V peak with a 50 µs rise, protecting the control electronics from nearby inductive loads. For installations subject to mechanical motion, the timer endures 2.5 g sinusoidal vibration, maintaining reliable contact alignment during operation.
