Note: 1. Specify both the model number and supply voltage when ordering for the H3CA-8H and H3CA-8.
2. The operation/resetting system depends on the selected operation mode. For details, see Timing Chart.
3. The 8 operation modes are as follows:
A: ON-delay operation E: Interval operation
B: Repeat cycle operation F: One-shot and flicker operation
C: Signal ON/OFF-delay operation (1) G: Signal ON/OFF-delay operation (2)
D: Signal OFF-delay operation (1) H: Signal OFF-delay operation (2)
