0743885-211
The 0743885-211 high-speed electronic counter from Danaher in the Timers and Controllers series offers robust performance and exceptional visibility for demanding industrial automation environments. Featuring a 12.7 mm (0.5 in) Red LED display and six decades of counting capacity, this unit provides clear readouts even in low-light or remote locations. The counter operates on a dual power requirement of 105-120 VAC or 210-250 VAC at 50/60 Hz, consuming only 1.5 watts for energy-efficient operation. Its maximum count speed of 1500 cpm (25 Hz) accommodates high-frequency input pulses without sacrificing accuracy, while the minimum impulse on/off-time of 0.02 seconds (20 ms) supports irregular signal patterns. Designed for flexibility, it maintains consistent performance across an operating temperature range of 0°C to +55°C and can be stored safely between -40°C and +74°C.
Performance is enhanced by the 105-120 VAC or 210-250 VAC count impulse voltage inputs, ensuring compatibility with both lower and higher voltage systems. The counter’s 12-inch color-coded wire leads simplify wiring and identification, reducing installation time. Reset options include a manual side pushbutton switch or a remote contact that accepts 5 VDC at 5 mA, requiring a minimum 100 ms closure for reliable operation. The unit’s maximum impulse on/off-time: unlimited enables continuous monitoring without timing constraints. Constructed with a zinc diecast frame and aluminum covers, the counter exhibits excellent mechanical stability and resistance to industrial wear.
Reliability is paramount: the diecast zinc frame and aluminum enclosure provide rugged protection against vibration and shock in harsh environments. Integration into control panels and machine enclosures is straightforward thanks to standardized dimensions and clear lead labeling. The device’s robust design supports seamless interfacing with PLCs, sensors, and actuators in factory automation lines. Typical applications include production line monitoring, machine cycle counting, and batch process control where high count rates and dependable performance are essential. With its combination of precision timing and industrial-grade construction, the 0743885-211 counter delivers the reliability and flexibility demanded by modern automation systems.
