B. Working Principle

The Omron H3CR-A timer works by receiving an electrical supply input and internally controlling the timing operation using an electronic timing circuit.

When the input signal is applied, the timer starts counting according to the selected time setting and operating mode. After the preset time is completed, the internal relay output changes its contact position to control connected devices such as motors, contactors, solenoid valves, alarms or other automation components.

The user can select different timing functions depending on the application requirement, such as:

• ON Delay: Output activates after the preset delay time.
• OFF Delay: Output remains active for a preset time after input removal.
• Interval Timing: Output operates for a defined duration after triggering.
• Cyclic Timing: Output switches repeatedly according to preset ON and OFF intervals.

The 11-pin configuration provides flexible wiring options for power supply, input trigger and relay output connections.
