software updates to your
device. See page 48, Field
Software Update, for more
information.
Description
The 9950 Dual Channel Transmitter is a two channel controller that can support
two sensors of same or different types in one instrument. The sensor types
supported by the 9950 are Signet Flow, pH/ORP, Conductivity/Resistivity, Salinity,
Temperature, Pressure, Level, Dissolved Oxygen, and devices that transmit a
4 to 20 mA signal with the use of the 8058 iGo
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 specifi c day or days of the week at a specifi c time.
The 9950 supports the following relay modules:
•
Four Channel Mechanical Relay Module
•
Two Mechanical and Two Solid State Relay Module
•
Two Mechanical Relays and Four Binary Inputs Module
for
Compatibility
The 9950 is compatible with all GF Signet
products listed in the column to the right.
● pH and ORP electrodes require the
Signet 2750 or 2751 DryLoc
Electronics (sold separately).
● Conductivity/Resistivity
measurement requires the Signet
2850 Conductivity/Resistivity Sensor
Electronics (sold separately).
