Industrial Applications

1. High-Speed Assembly Line Sorting

Utilizing the universal transistor output, the H3CR-AS acts as a high-cycle delay trigger for sorting actuators, receiving sensor feedback and triggering gates without mechanical contact wear.

Problem Solved

Prevents frequent contact wear and failure typical of mechanical relay timers in high-frequency sorting applications.

2. Automated Machine Lubrication Cycling

Configuring the timer in Flicker ON or OFF start modes allows automatic periodic activation of grease or oil pumps at precise intervals over hours-long ranges.

Problem Solved

Maintains rigid, unattended repeat-cycle timing sequences to keep machines lubricated without custom PLC code.

3. Conveyor Jam and Feed-Interruption Detection

With a proximity sensor wired to the no-voltage input, the timer is reset by moving parts on a conveyor using the Signal OFF-delay mode; if flow stops, the output triggers an alarm.

Problem Solved

Detects production-line blockages locally at the conveyor section without needing a central PLC module.
