The response time is the time it takes for the main contact to open after the input is turned OFF. The insulation resistance was measured with 500 VDC at the same places that the dielectric strength was checked. For 100 to 240-VAC type, add approximately 20 g.

Make sure that the whole safety control system meets EN954-1 requirements. Wiring Turn OFF the G9SA before wiring the G9SA. [. . . ] When an Expansion Unit is being used, remove the connector cover from the G9SA Safety Relay Unit (G9SA-301, G9SA-501, G9SA321#, or G9SA-TH301) and insert the connector of the Expansion Unit's connector cable. G9SA G9SA Earth Short A positive thermistor is built into the G9SA circuits, so you can detect earth short breakdowns and breakdown shorts between channel 1 and channel 2. If the short breakdown is canceled, reset is automatic. G9SA G-121 G9SA ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
