Rated supply voltage AC/DC 24 - 240 V, 0/50/60 Hz, < 4 W, < 8 VA DC: 20,4 ... 297 V, AC: 20 ... 264 V < 2 W, < 6 VA
Overload capacity 100 A / 300 A
Ambient temperature range -20...+55 °C
Protection housing IP 30
Protection terminals IP 20
Applied standards UL/CSA

The current relay STW81V is an 8-channel AC current relay, designed for controlling of suction plants e.g. in the timber and plastics processing industry. When there is an AC-current >1A through one of up to 8 connected transformers type STWA1, the appropriate relay K1...K8 (1 x co) picks up and opens the slide valve of the machine. At the same time the relay K9 starts the central suction.

Relays K1...K8 switch off 10s after the current flow through the appropriate transformer is 0. K9 switches off 0...60s (adjustable) after the current in all transformers is 0.

Application

The current relay STW81V is particularly suitable for the central control of slide valves in suction plants, which are to be operated dependent on operating condition of individual machines. It can control a central suction at the same time.

  • single evaluation of 8 inputs with STWA1
  • single evaluation of 8 inputs with current-sensor S1
  • inputs for 8 potential-free contacts
  • OR-evaluation of all circuits (K9)
  • 9 output relays
  • LED display for relays / inputs
  • Switching point adjustable 0,5 - 5 A
  • switch-off delay of K9 adjustable 0 - 60 seconds
  • switch-off delay single relays 10 s
  • last relay: K9 + 20 s
