Part number

AC 220 - 240 V
AC/DC 24 V

Product description

 

Current relay in OR evaluation with 8 inputs, designed e.g. for controlling of suction plants in the timber and plastics processing industry. When there is an AC-current >1 A through one of up to 8 connected transformers STWA 1, the integrated relay (1co) picks up. When all currents are 0, the relay releases with a delay of approx. 10s. This enables a run-after of the central suction.

  • 8 inputs
  • OR-evaluation
  • relay picks up if at least 1 input is activated
  • operating value approx. 1 A
  • turn-off delay approx. 10 s
  • not necessary inputs remain open
  • options
    - switch-on delay 3 s
    - without switch-off delay
