This relay from Schmersal enhances workplace safety in automated industrial applications. It can signal emergency stop commands to potential-free outputs – such as position switches – and control the flow of energy to potentials, like safety-light grids. The unit's feedback circuit offers high levels of reliability by preventing contact-point failure and ensuring continuous operation of the unit. Snap-on DIN-rail mounting allows for quick control-panel installation or removal. The device delivers high-speed function combined with low power requirements.

• Time-saving automatic reset function
• Self-cleaning contacts to prevent the build-up of non-conductive deposits
• Ventilated housing that quickly dissipates heat to keep operating temperature cool and improve efficiency
• Meets EN 954-1 Category 4 safety parameters so maintains its safety function even with an accumulation of undetected faults

• Process handling
• Robotics
• Medical industry
• Food processing

This Schmersal relay is compact and lightweight for improved efficiency and packing capacity in your control panel. Its dimensions are 100 (H) x 45 (W) x 121 (D) mm, and it weighs just 240 g.
