Safety/Relay Unit G9SA
Caution
Product Description
A small and ultra-thin relay unit for safety and industrial uses. The product series features a wide array of types.
[Features]
· Four kinds of 45-mm wide units are available: a 3-pole model, a 5-pole model, and a model with 3 poles + 2 OFF-delay poles, as well as a two-hand controller.
· Also available are 17.5-mm wide expansion units with 2-poles and 3-poles, and 22.5-mm units with 3 OFF-delay poles.
· The expansion units can be connected in a single action.
· Can be DIN track mounted or screw mounted. OFF-delay types have 15-step OFF-delay settings.
· Conforms to EN ISO13849-1 (PLe/Safety Category 4) (G9SA) and European EN standards (G9SB). TÜV certified (G9SB).
· When it receives a signal from an input unit such as an emergency stop switch, it sends a signal to the output (contactor etc.) depending on whether it is judged to be safe or not.
[Applications]
· Can be used as device which ensures that operations only commence if it is deemed safe to do so.
