ZIEHL industrie-elektronik, 74523 Schwäbisch Hall, Germany, +49 791 504-0, info@ziehl.de, www.ziehl.de 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 connec- ted 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 Current-Relay STW1K AC-Detection, OR-Evaluation of 1-8 Transformers 0123 78 1 6 1 5 1 84 5 6 A2 A1 1 .... 8 Stromwandler/ current transformer STWA 1(H) STWA1H (+) = 1...8 STWA1H (-) = 0 Us Absaugung/ central suction N M 3 ~ Maschine/ machine STW1K M 3 ~ Technical Data Rated supply voltage Us Transformer input Overload cap.continous/max 10s Function Switching point on Switching point off Switch-off delay Switch-on delay Output relay Type of contact Test conditions Rated ambient temperature range Dimensions (h x w x d) Attachment Protection housing / terminals Weight AC 220 - 240 V +10-15%, < 3 VA, 50/ 60 Hz AC/DC 24 V, DC 21-30 V, AC 20,4-26,4 Hz 1…8, type STWA , order-number S 225201
