Current Transducer H931

Features

  • Loop powered analog current transducer with integral start/stop command relay
  • Reduces the number of installed components, saves time and space
  • Self-gripping, split-core design for fast retrofit installation, no need to remove conductor
  • Reduces installation charges – one device to install for start/stop and status
  • Fewer wires – power the current sensor and receive the 4 to 20 mA signal with only two wires
  • Selectable factory calibrated ranges up to 120 A for increased flexibility and resolution
  • 30 mA at 12 to 30 VDC sensor power
