Shunt Automatic detection of AC/ DC Monitoring of over- or under- current Adjustable range 10...100% I N Hysteresis adjustable 5...50% Start-up delay 1...20s (input enable) Switching delay 0,1...10s for fading of short peaks Output-relay 2 changeover- contacts (co) Operating- or closed-circuit- mode for relays selectable with bridge Current Relay for DC- and AC-currents AC/DC 0,1 - 10 A, 60 mV with external shunt ZIEHL current-relays STW1000 have 4 measuring-ranges. They monitor most of the common AC- and DC-currents for over- or undercurrent. Currents up to 10 A can be connected directly to the STW. For higher currents external transformers (to inputs 1/5 A) or Shunts (input 60 mV) can be connected.
