DA1110A301

The DA1110A301 precision repeat cycle timer from Danaher is a robust component within the Timers and Controllers series designed for demanding industrial automation environments. This solid-state electronic timer operates on an operating voltage of 115 or 230 VAC with a ±10 V voltage variation, ensuring compatibility across common power systems. With a speed of 1000 counts per minute, it delivers fine-grained timing control while maintaining a minimum on/off time of 30 ms for rapid cycle transitions. Drawing only 6 W of power, the DA1110A301 provides efficient performance without compromising on durability. Its structural integrity is bolstered by a frame & covers material of Zamak, which offers excellent mechanical strength and corrosion resistance.

Equipped with carefully engineered internal components, this timer employs a bobbin material of Nylon and wheels & pinions made from Plastic to facilitate smooth, wear-resistant operation in continuous repeat cycle timing. The number of figures is 6, enabling precise configuration of multiple timing parameters via its analog dial interface. Electrical connections utilize #22 AWG leads of 7.5 in (190 mm) length exiting from the lead exit at the bottom of the unit, streamlining installation in panel-mounted assemblies. The figure size of 0.188 in H × 0.156 in W ensures compactness without sacrificing readability of calibration markings. Additionally, the reset type is Manual rotary or lock and key, providing secure and intentional resetting of timing cycles when required.

Operationally, the DA1110A301 excels through its combination of high count rate and precise minimum timing resolution. The minimum on/off time of 30 ms allows for rapid state changes, while the speed of 1000 cpm supports high-frequency pulse generation for repetitive control tasks. Consistent performance under variable supply conditions is guaranteed by its ±10 V voltage variation tolerance, and the modest power consumption of 6 W minimizes heat generation in enclosed control panels. The bottom lead exit design simplifies wiring in DIN-rail or chassis environments, and its moderate net weight (panel mount) of 1 lb 4 oz (567 g) ensures secure mounting without excessive structural support. The unit’s durable Zamak housing further protects internal mechanisms from mechanical shock and environmental contaminants.

Integration of the DA1110A301 into industrial control systems is straightforward, thanks to its standard panel-mount form factor and clear calibration markings on all six figures. Reliable analog setpoint adjustment is facilitated by calibrated knobs that maintain precision over extended duty cycles, while the manual rotary or lock and key reset type prevents unintended resets during critical operations. With its compact frame & covers material of Zamak, bottom lead exit, and versatile operating voltage range, this timer is ideally suited for applications including conveyor indexing, batch process control, packaging machinery, and repetitive machine tool sequencing. Its combination of high-speed timing, robust construction, and flexible reset options makes the DA1110A301 an excellent choice for engineers seeking reliable repeat cycle control in industrial automation.
