For contact input, use gold-plated contacts to make sure that the residual voltage is less than 1V when the contacts are closed.

Power

For transistor input, use transistors with the following specifi cations; VCE = 40V, VCES = 1V or less, IC = 50 mA or more, and ICBO = 50µA or less. The resistance should be less than 1k when the transistor is on. When the output transistor switches on, a signal is input to the timer.

Inputs: GT3A-1, -2, -3

Transistor output equipment such as proximity switches and photoelectric switches can input signals if they are voltage/current output type, with power voltage ranges from 18 to 30V and have1V. When the signal voltage switches from H to L, a signal is input to the timer

Reset Input When the reset input is activated, the time is reset, and contacts return to original state. Start Input The start input initiates a time-delay operation and controls output status.No-voltage contact inputs and NPN open collector transis-tor inputs are applicable.24V DC, 1mA maximum Input response time: 50msec maximum Gate Input The time-delay operation is suspended while the gate input is on (pause).
