Ultra Slim Safety Relay Unit • Models of width 17.5 mm available with 2 or 3 poles. Models of width 22.5 mm with 3 poles also available. • Conforms to EN standards. (TUV approval) • DIN track mounting possible. A Be sure to read the “Safety Precautions”on page 9. Model Number Legend Note: Please see “Ordering Information” below for the actual models that can be ordered. 5. Input Configuration None: 1-channel or 2-channel input possible 0: None (direct breaking) 6. Miscellaneous A: Auto-reset, inverse input B: Auto-reset, + common input C: Manual reset, inverse input D: Manual reset, + common input 1. Function None: Emergency stop 3. Contact Configuration (OFF-delay Output) 0: None4. Contact Configuration (Auxiliary Output) 0: None 1: SPST-NC Note: 1. Relays with inverse inputs are used mainly when inputting signals from two mechanical switches. 2. Relays with positive commons are used mainly when inputting signals from a safety sensor or from one mechanical switch. * The G9SB-3010 can be applied to Safety Category 3 of the EN954-1 if double breaking is used.

Specifications Ratings Power Input *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 durability is for an ambient temperature of 15 to 35°C and an ambient humidity of 25% to 75%.

Connections Internal Connections G9SB-2002-A/C (24 VAC/VDC) G9SB-3012-A/C (24 VAC/VDC) Note: 1. 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. Always provide a protective ground externally, e.g., on the power supply. * Only G9SB-301 □-□ models have terminals 33-34 and 41-42. Note: Grounding Be sure to ground externally, such as at the power supply. (1) G9SB-3010 directly cuts off power, and has no Safety Input. (2) For 1-channel input with G9SB-@@@-B/D, short circuit T12-T22 and then input. (3)...

Safety PrecautionsBe sure to read the Common Precautions for Safety Warning at the following URL: http://www.ia.omron.com/. ^CAUTION Turn OFF the G9SB before wiring the G9SB. 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. Precautions for Correct Use Failure Detection for Slow-starting Power Supply When using a power supply with a long start-up time, if power is switched on while input has been closed the internal circuits will detect a power voltage error and the product will not operate. Apply the voltage...
