Note: 1. With 100 to 240-VAC type, be sure to connect PE to a protective
ground. With 24-VAC/VDC type, if the power supply is not
connected to a protective ground, be sure to connect PE to a
protective ground.
2. With 24-VAC/VDC type, the power supply terminals A1 and A2
have polarities. A2 is the negative pole.
*1. Use terminals A and B to switch reset mode.
A to B open: Manual reset
A to B closed: Auto-reset
*2. Terminal T23 is used for 2-channel input with a positive common
(when connecting a safety sensor with a PNP output).
When using T23, make sure that T21 and T22 are open.
For 1-channel input, make sure that T12 and T23 are shorted.
*3. Terminals 43-44 and terminals 53-54 are OFF-delayed outputs.

Wiring of Inputs and Outputs
*1. Terminal T23
Terminal T23 is used for 2-channel input with a positive common (when connecting a safety sensor with a PNP output). When T23 is being
used, please open T21 and T22. For 1-channel input, short circuit T12-T23 before use.
*2. Output Contacts
G9SA-301: Safety Output Contacts 13-14, 23-24, 33-34. Auxiliary Contact 41-42.
G9SA-501: Safety Output Contacts 13-14, 23-24, 33-34, 43-44, 53-54. Auxiliary Contact 61-62.
G9SA-321-T@: Safety Output Contacts 13-14, 23-24, 33-34. Safety OFF-delay Output Contact 43-44, 53-54. Auxiliary Contact 61-62.
*3. Terminals A and B
A-B Opening: Manual Reset
A-B Short Circuit: Auto Reset
Signal name Terminal name Description of operation
Power supply input A1, A2 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.
Safety input 1 T11, T12 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.
Safety input 2 T21, T22, T23 *1
Feedback/reset input T31, T32 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.
Instantaneous safety outputs See below. *2Turns ON/OFF according to the state of the safety inputs and feedback/reset inputs. During OFF-delay
state, the Instantaneous safety outputs are not able to turn ON.
OFF-delayed safety outputs See below. *2 OFF-delayed safety outputs. The OFF-delay time is set by the OFF-delay preset switch.
Auxiliary output See below. *2 Synchronized with Instantaneous Safety Output.
Manual/Auto selector input A, B *3 Switch between Auto Reset and Manual Reset modes.
Ground terminal PE
Be sure to connect the PE terminal to a protective earth for 100-240 VAC models.
Where the 24 VAC/VDC model power supply is not grounded, lease be sure to connect the PE to a
protective earth.
