Features

  • Dual sensor input
  • Display and/or control: μS, mS, PPM or PPB (TDS), kΩ, MΩ, % rejection, difference, ratio, °C or °F
  • Three fully scaleable 4 to 20mA outputs
  • Two open collector outputs; Four programmable relays
  • Time delay relay function
  • Proportional pulse control capability
  • Compatible with ALL Signet conductivity electrodes
  • Programmable temperature compensation
  • NEMA 4X/IP65

The GF Signet 8860 Two-Channel Conductivity Controller is packed with a set of features and capabilities ideal for the real needs of water treatment applications. The GF Signet 8860 Two-Channel Conductivity Controller accommodates two separate and independent input sources and can be powered with AC or 24VDC. Programmable via a simple and intuitive menu system, the GF Signet 8860 Two-Channel Conductivity Controller can also be programmed to measure a raw conductivity value by turning off the temperature compensation mode, hence meeting USP requirements.

To control the process, the GF Signet 8860 Two-Channel Conductivity Controller is equipped with four dry contact relays and three 4 to 20mA output loops. Calculated measurements include: Difference, Ratio or % Rejection. Two of the relays may be converted into open collector outputs with the flip of a switch. Operating modes for the relays and open collector outputs are high or low alarm, pulse, or special USP alarm mode. The GF Signet 8860 Two-Channel Conductivity Controller is offered with a NEMA 4X/IP65 front panel with a self-healing window in a 1/4 DIN package for easy panel installation.
