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
Semiconductor outputs for wear-free operation
DIP-switch configurable for fast setup/customized function
Removable spring-type terminals for fast installation
Certified to PLe category (EN/ISO 13849-1) standards

The G9SR Advanced Unit is 22.5 mm wide and has single or double channel safety inputs, plus double channel safety relay outputs rated at 5 A. For applications where input expansion is needed, each advanced unit can control up to two G9SR basic units that are configured as additional safety inputs to the same safety function.

The G9SR Extension Unit is 22.5 mm wide and has three safety relay outputs rated at 5 A. These outputs can be configured for instantaneous operation or to provide independent safe on and off delay timers that can be set in sixteen steps to give a maximum delay of 90 seconds. Up to three G9SR output expansion units can be connected to an advanced unit to provide one instantaneous safety output on the advanced module plus three time controlled safety outputs on the extension units.
