Omron Dual-Channel Emergency Stop Safety Relay, 24V ac/dc, 3 Safety Contacts

The Omron G9SB series is an ultra slim safety relay available in either a 17.5mm or 22.5mm housing. The 17.5mm units have 2 or 3 safety contacts and the 22.5mm units have 3 safety contacts and an auxiliary contact.

1 and 2 input channel units
Manual and automatic reset units
Certification up to category 4 according to EN954-1 (depending on the application)
Can also be used with safety sensors F3SN, F3SH, F3S-B, F3STGR, F3SL, F3S-J
Conforms to EN standards (TUV approval)

When ordering take note of the safety reset mode that is required: Models G9SB**A and G9SB ** B = Auto Reset operation; Models G9SB ** D = Manual Reset operation
