- 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
