Description

The 9950 is a multi-channel, multi-sensor transmitter designed to meet and exceed the
industry standards, and expectations for a small, compact, ¼" DIN transmitter. The power
and versatility of the 9950 allows the use of up to six GF sensors to manage complex water
treatment applications.
The 9950 analyzer supports all like sensors or a mix of any GF sensors. 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.
The 9950 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 six outputs.
Four Conductivity sensor measurements are supported with either a single or dual channel
conductivity module. If six conductivity sensors are required, the use of a 3-2850-51-XX
can be added to the main S³L input terminals.
The 3-9950.393-3 Relay Module provides four binary inputs that are compatible with any
open collector or mechanical contacts, such as level switches, fl ow switches, pressure
switches or other devices. 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.
The 9950 supports the following modules:
• Four Channel Mechanical Relay Module
• Two Mechanical and Two Solid State
Relay Module
• Two Mechanical Relays and Four Binary
Inputs Module
• Single Channel Conductivity
Resistivity Module
• Dual Channel Conductivity Module
English
• Dual Channel 4 to 20 mA Current Loop
Output Module
• Modbus Module

Compatibility

• pH/ORP electrodes require the GF 2751
DryLoc® Sensor Electronics
(sold separately).
• Conductivity/Resistivity measurement
requires the GF 2850 Conductivity/Resistivity
electronics or a single or dual conductivity
module and proper conductivity sensor
(sold separately).
