Part number

5-30 A adjustable

Product description

 

Recording of welding currents (mounting at ground wire) for controlling dedusting plants in combination with ZIEHL-controls type STW. Recording the state of a consumer of electricity (on or off or defective).

In general the current-sensor S1 is used where the current-flow is to be detected, with the exact value of the current either known from the power consumption of the connected consumer or does not matter for the evaluation.

For evaluation of measuring data in more than 1 cable, these outputs of several current-sensors can be connected in parallel (OR-evaluation).

  • switching point app. 5 A (option: adjustable 5-30 A)
  • monitoring of AC and DC currents
  • LED for current flow
  • mounting without disconnection of cable possible
  • 2 transistor-outputs, switching + and -, direct connection to a PLC possible
  • connection to current-relays ZIEHL type STW
  • robust, sealed execution
  • overload capacity: unlimited
