H3CA

Solid-state Timer

H3CA

DIN-sized (48 × 48, 45 × 75 mm) Timer with Digital Setting and LCD Display

Time Ranges

A desired time can be set within a range of 0.1 s to 9,990 hrs by combining the three thumbwheel switch modules for time setting and one module for time unit selection.

Time unit 0.1 s 1 s 0.1 min 1 min 0.1 hrs 1 hr 10 hrs
Time range 1 to 999 (3 digits)
