BC 6587 & BC 7687

Universal 4-20mA Input Controllers

These instruments are used when there is a need to add display functions, control, alarm, and / or automatic cleaning of the sensor to a transmitter capable of performing any type of measurement. 

These instruments provide:

  • ABS watertight enclosure, with Polycarbonate front panel
  • Measuring display in the selectable range from -9999 to 9999, corresponding to the 0-20 mA or 4-20 mA input
  • VDC power to power the 4-20 mA loop of the transmitter
  • Automatic measurement control function
  • Alarm from the low/high measurement, the set point overtime operation and the logic input
  • Programmable dual analog output for recording and acquisition of the measurement values or PID regulation
  • Hold / alarm function activated by two external volt free contacts
  • Automatic /manual autoclean function

This unit allows a differential measurement, by using two 0-20 mA or 4-20 mA transmitters featuring the same measurement scale.
