The STW81V current relay is supplied with a switch-off delay of 0s and a set switching threshold of 0.5
4 Application and brief description
The STW81V current relay is an 8-fold AC current meter with individual evaluation of 8 current
circuits and OR connection of all inputs.
Usage:
The STW81V current relay is particularly suitable for the central control of gate valves in extraction
systems to be actuated according to the operating status of individual machines. It can
simultaneously control the central extraction system.
