- The current relay STW84V monitors up to 8 alternating current sets on current flow yes/no. The inputs can analyse signals of current transformers type STWA1(H) or of potential-free contacts.
- For controlling of great dedusting plants several relays can be combined.
- run-after last slide-valve 0... 99 s
- turn-off delay ventilator 0...99 s
- minimum volume-flow 1...100 %, (if necessary automatic opening of additional slide-valves, beginning with K8)
- maximum volume-flow 5... 100 %
- 7-segment-display for settings during programming, in operation display of the volume flow
- 8 LEDs for input/output selection and display of the active inputs/outputs
- 9 LEDs for function selection
- easy programming
