The ATC 365A 300 Q 30PX Long-Ranger Timer is a microprocessor-based computing timer engineered for industrial timing and control applications demanding precision and reliability. This digital timer delivers repeat accuracy of ±0.10 seconds across a selectable timing range from 0.01 seconds to 999 hours, with nine available ranges covering seconds, minutes, and hours. The unit features a high-brightness vacuum fluorescent display, dual 7A DPDT relay outputs, and instantaneous cycle shortening through real-time setpoint re-computation—all within a compact 72 mm² DIN housing that consumes 40% less panel space than conventional designs.
