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.
