Product Overview
The Omron G9SE-201 is a safety relay unit designed for emergency stop and safety circuit applications in industrial machinery. This relay provides 2 normally open (NO) safety contacts that are forced-guided to ensure reliable operation in safety-critical applications. The G9SE-201 operates on 24VDC power supply and is suitable for use in safety circuits up to Category 4 per EN ISO 13849-1 and SIL3 per IEC 61508. The forced-guided contacts ensure that if the contacts fail to open, they cannot be closed, providing fail-safe operation required for safety applications. The compact 22.5mm width allows for space-efficient panel installation on DIN rail. The G9SE-201 features LED indicators for power and contact status, enabling quick diagnostics. This safety relay is ideal for emergency stop circuits, safety door monitoring, and other safety interlock applications in manufacturing equipment, packaging machinery, and assembly systems.
