Relays with inverse inputs are used mainly when inputting signals from two mechanical switches.
2.
Relays with positive commons are used mainly when inputting signals from a safety sensor or from one mechanical switch.

The contact resistance was measured with 1 A at 5 VDC using the voltage-drop method.
Not including bounce time.
The response time is the time it takes for the main contact to open after the input is turned OFF. Includes bounce time.
The insulation resistance was measured with 500 VDC at the same places that the dielectric strength was checked.
The durability is for an ambient temperature of 15 to 35°C and an ambient humidity of 25% to 75%.

Always provide a protective ground externally, e.g., on the
power supply.

Description of operation
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.
Note:
Grounding
Be sure to ground externally, such as at the power supply.

Safety Inputs
(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.
*2.
Output Contacts
G9SB-2002-A/C: Safety Output Contacts 13-14, 23-24.
G9SB-3012-A/C: Safety Output Contacts 13-14, 23-24, 33-34. Auxiliary Contact 41-42.

Application Overview
•
The power supply to the motor M is turned OFF when the S1 and S2 detect that the guard is opened.
•
The power supply to the motor M is kept OFF until the guard is closed.
