For 1-channel input with G9SB-@@@-B/D models, short terminals T12 and T22. It is not possible to wire G9SB-@@@2-A/C models for 1-channel input. 2. Only G9SB-301@-@ models have terminals 33-34 and 41-42. 6 G9SB G9SB Precautions Wiring Turn OFF the G9SB before wiring. Do not touch the terminals of the G9SB while the power is turned ON, because the terminals are charged and may cause an electric shock. T11 T12 Use the following to wire the G9SB. Stranded wire: 0.2 to 2.5 mm2 Solid wire: 0.2 to 2.5 mm2 Tighten each screw to a torque of 0.5 to 0.6 N·m, or the G9SB may malfunction or generate heat. External inputs connected to T11 and T12 or T21 and T22 of the G9SB must be no-voltage contact inputs. Applicable Safety Category All G9SB Relays meet the requirements of Safety Category 4 of the EN954-1 standards when they are used as shown in the examples provided by OMRON. Relays may not meet the standards in some operating conditions. The G9SB-3010 can be applied to Safety Category 3 of the EN954-1 using double breaking. G9SB T11 T12 G9SB Earth Short A positive thermistor is built into the G9SB circuits, so you can detect earth short breakdowns and breakdown shorts between channel 1 and channel 2. (Detection of breakdown shorts between channel 1 and channel 2 is supported for G9SB-2002- @/ 3012- @ models only.) Note In order to detect earth short breakdowns, connect the minus side of the power supply to ground. The applicable safety category is determined from the whole safety control system. Make sure that the whole safety control system meets EN954-1 requirements. Mounting Multiple Units When mounting multiple Units close to each other, the rated current will be 3 A. Do not apply a current higher than 3 A. Connecting Inputs If using multiple G9SB models, inputs cannot be made using the same switch. This is also true for other input terminals. 7 G9SB G9SB ALL DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527. Cat. No. J130-E1-1 In the interest of product improvement, specifications are subject to change without notice.
