The 9950 Conductivity Transmitter is a two channel controller that can support two sensors in 
one instrument. The sensor types supported by the 9950 are the Signet Conductivity/Resistivity 
sensors.

The 9950 includes advanced features such as derived functions, advanced multiple relay 
modes, and timer based relay functions. Derived functions allows for the control of a relay or 
current loop with the sum, delta (difference), or ratio of two measurements. Multiple relay modes 
allow up to three signals to be used for the control of a single relay, and can be any combination 
of analog and binary inputs. The timer relay modes allow a relay to be activated on a repeating 
basis from every minute to once every 30 days. Weekday timer mode allows a relay to be 
energized, on a speci

fi

 c day or days of the week at a speci

fi

 c time.

Your 9950 system may include the following modules:

• 

Direct Single Channel Conductivity Resistivity Module

• 

Dual Channel Conductivity Resistivity Module

• 

Four Channel Mechanical Relay Module (Optional)

• 

Two Mechanical and Two Solid State Relay Module (Optional)

• 

Two Mechanical Relays and Four Binary Inputs Module (Optional)

The 9950 Conductivity Transmitter is compatible with the Conductivity sensors listed in 
the table below.

• 

Conductivity/Resistivity measurement requires the conductivity resistivity module 
or Signet 2850 Conductivity/Resistivity Sensor Electronics (sold separately).
