Schmersal PROTECT Safety Relay, Single or Dual Channel, 24 V AC/DC - SRB 324ST Series - SRB324ST 24V (V.3)

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.

Features and Benefits

• 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

Application Information

• Process handling

• Robotics

• Medical industry

• Food processing
