Input Configuration None: 1-channel or 2-channel input possible Ordering InformationSafety Relay UnitEmergency-stop Unit with Sensor Connector Main contact Note: 1. Connect to the sensor connector using a special OMRON F3SJ Safety Light Curtain Connecting Cable. For details, refer to the information on accessories below. 2. The Safety Light Curtain and Connecting Cable are sold separately. Connecting Cables (for F3SJ - G9SA-300-SC connection only) Appearance Note: 1. The model numbers given in the table are for sets of two Cables, one for the emitter and one for the receiver. 2. F3SP-JDDD (F3SJ - F3SP-B1P Connecting Cables) cannot be used.

Specifications Ratings Power Input 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 turn OFF 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.

Safety Precautions Precautions for Safe Use Refer to the “Precautions for All Relays” and “Precautions for All Relays with Forcibly Guided Contacts”. Failure Detection for Slow-starting Power Supply • Turn OFF the G9SA-300-SC before wiring the G9SA-300-SC. Do not touch the terminals of the G9SA-300-SC while the power is turned ON, because the terminals are charged and may cause an electric shock. • To conform to IEC61496-1 and UL508 when using the F3SJ ensure that the DC power supply satisfies all the conditions below. • The voltage is within the rated power supply voltage range (24 VDC ±10%). •...
