| Specify the power supply voltage when ordering. Emergency-stop Units Note: Set to maximum values in the factory.

Power Input Item Model * When an Expansion Unit is connected, the power consumption is increased by 2 VA/2 W max. Inputs Item Model * When an Expansion Unit is connected, the input current is increased by 30 mA max. Contacts *1. The contact resistance was measured with 1 A at 5 VDC using the voltage-drop method. *2. Not Including bounce time. *3. The response time is the time it takes for the main contact to open after the input is turned OFF. Includes bounce time. *4. The insulation resistance was measured with 500 VDC at the same places that the dielectric strength was checked. *5. The...

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...

*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.
