Dayton 6-Digit Electromechanical Counter

The Dayton 1A789 is a 6-digit electromechanical counter designed for industrial automation and electrical control panels. It accepts a 24V AC input signal and mounts from the rear with a depth of 2.42 in. The display shows 0.17 in white numbers on a black background for clear visibility in control environments.

Thermal Noise and Power Draw

As an electromechanical device, the counter operates without active cooling and produces no audible fan noise. Power draw is limited to the 24V AC coil consumption during each count pulse. The unit registers up to 10 counts per second with a minimum on/off pulse of 50 msec each, making it suitable for moderate-speed sequencing tasks.

Replaces Manual Tally and Upgrades From Basic Timers

This counter replaces manual tally methods and upgrades from simple elapsed-time meters when a discrete event total is required. The jump is worth it for processes that need a permanent, non-volatile count without a reset function. It is not suited for applications requiring high-speed counting beyond 10 counts per second or for systems needing a zero-reset capability.

Questions about this item

How do I install the 24VAC base-mount counter and what wiring mistake should I avoid?

Mount the unit rear-facing using the 2.36 in height by 1.63 in width footprint, then connect the 24V AC input signal wires; the common error is reversing the AC leads which prevents the 10 counts-per-second mechanism from advancing.

What maintenance or replacement will the 6-digit electromechanical counter need over time?

The white-on-black display digits and internal gear train are sealed with no reset function; plan to replace the entire counter once the 0.17 in numerals become illegible or the mechanism exceeds its rated pulse life.

What is the first limit that appears during continuous high-speed counting?

The 10 counts-per-second maximum is reached first; pulses shorter than the 50 msec on / 50 msec off minimum will be missed before any thermal or voltage limit occurs.
