(1) G9SB-3010 directly cuts off power, and has no Safety Input.
(2) For 1-channel input with G9SB-@@@-B/D, short circuit T12-T22 and then input.
(3) With G9SB-@@@2-A/C, 1-channel input wiring is not possible.

The input terminals for power supply. Connect the power source to the A1 and A2 terminals.
DC inputs have polarity, so A1 should be connected to the positive side and A2 to the negative side.
To set the safety outputs in the ON state, the ON state signals must be input to both safety input 1 and
safety input 2. Otherwise the safety outputs cannot be in the ON state.
To set the safety outputs in the ON state, the ON state signal must be input to T31 - T32. Otherwise the
safety outputs cannot be in the ON state.
Turns ON/OFF according to the state of the safety inputs and feedback/reset inputs.
Synchronized with Instant Safety Output.
