  • Up to four on board relays via optional modules, and up to 4 external DIN Rail mounted Relays via optional 8059 module (six input option only)
  • The 9950 supports any one of the following relay modules:
    • Four Mechanical Relay Module
    • Two Mechanical and Two Solid State Relay Module
    • Two Mechanical Relays and Four Binary Inputs Module
  • Optional Modbus RTU Module for connections to Serial RS485 automation networks
  • Derived measurements - Delta, SUM and Ratio
  • Advanced boolean logic - A | B | C, A & B & C, A | (B & C), A & (B | C)
  • NEMA 4X/IP65 (front face only)


The GF Signet 9950 Six Channel base unit comes complete with two each 4 to 20 mA output, two additional dual 4 to 20 mA output modules can be installed to increase the number of 4 to 20 mA outputs to a total of 6 outputs. Four Conductivity sensor measurements are supported with either a single or dual channel conductivity module. If 6 conductivity sensors are required, the use of a 3-2850-X1-XX can be added to the main S³L input terminals.

The 9950 offers advanced features such as derived functions, advanced multiple relay modes (Boolean logic), and timer-based relay functions. The 9950 Modbus Module allows for remote access to primary and secondary measurements, derived functions, status of current loop outputs and relays, over a serial RS485 Modbus automation network.

Sensor types and accessories supported by the 9950 are GF Flow (Frequency and/or digital S³L), pH/ORP, Conductivity/Resistivity, Salinity, Temperature, Pressure, Level, Dissolved Oxygen, and any device that transmits a 4 to 20 mA signal when used with the single channel 3-8058 iGo® Signal Converter.
