Omron Advanced Unit G9SR Emergency Stop Safety Relay, 24V dc, Single/Dual-Channel, 2 Safety Contacts

The three models of the Omron G9SR safety relays cover virtually all common control system safety requirements in standalone applications. They feature front-panel DIP switches for fast, easy configuration and customization, together with LED indicators for quick status monitoring and fault diagnosis.
The key characteristics of the G9SR include certification to category PLe in line with EN/ISO 13849-1, fast response time to ensure minimum stopping times, solid-state outputs for long-life wear-free operation, compact housings to save space in control panels and removable spring-type terminals to ensure rapid straightforward installation. All units are equipped with an additional monitoring output to provide diagnostic information for use by the standard control system.

The G9SR Basic Unit is just 17.5 mm wide and has single or double channel safety inputs, plus double channel solid state safety outputs. The outputs are rated at 2A, which makes them suitable for direct switching of even large contactors.

Compatible for a variety of safety solutions like E-Stop, guard monitoring devices, light curtains and others
Fast response time for short safety distance
