Model# CTH

Hall Effect DC Current Transducer

The CTH Series Current Transducer is similar to the CTG Series but offers a 4-20mA output signal or a 4-12-20mA bi-directional output signal. The CTH current transducer can be operated from either a 24Vdc source or a low cost 24Vac control transformer. Available options are split core, extended temperature range, ruggedized design and 15Vdc instrument power.

  • Sensor & Amplifier in one package
  • Split Core Available
  • Output is proportional in direction and magnitude to the input current flow through the window.

AVAILABLE OPTIONS – Add Suffix in order shown

  • Split Core: Add suffix “S”
  • Extended Temp. Range to (-40OC to +60OC): Add Suffix “T”
  • Ruggedized (potted): Add Suffix “R”
  • Instrument Power Types: for (15Vdc, +10.0%) Add Suffix “-15” or for (12Vdc, +10.0%)Add Suffix “-12”
  • Optional 24Vdc Power Supply available: TMP15124C
