Power
For transistor input, use transistors with the following specifications; VCE = 40V, VCES = 1V or less, IC = 50 mA or more, and ICBO = 50µA or less. The resistance
should be less than 1kΩ 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

Inputs: GT3A-4, -5, -6
Start Input
The start input initiates a time-delay operation and controls
output status.
Reset Input
When the reset input is activated, the time is reset, and
contacts return to original state.
Gate Input
The time-delay operation is suspended while the gate input
is on (pause).
No-voltage contact inputs and NPN open collector transis-
tor inputs are applicable.
24V DC, 1mA maximum
Input response time: 50msec maximum
