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.
