General Features

• One instrument for multiple sensor types
• Two different sensor types can be combined in one instrument
• Configurable display
• Derived measurements
• Optional modules can be added for additional capabilities
• USB Port for field upgrades using standard USB flash drive

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® Signal Converter.

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 modules:

• Four Channel Mechanical Relay Module
• Two Mechanical and Two Solid State Relay Module
• Two Mechanical Relays and Four Binary Inputs Module
• Direct Single Channel Conductivity Resistivity Module
• Dual Channel 4 to 20 mA Current Loop Output Module
• Dual Channel Conductivity Module • Modbus Module

NOTE: 3-9950-2
Before commissioning the device, make sure the supply voltage matches the voltage specifi cations on the nameplate. For DC power input and Loop current regulated voltage, use UL60950-1 or UL61010-1 certifi ed power supply. Power supply shall also be rated for operation at 4000 m altitude. Provide a suitable switch or circuit breaker the installation. This switch must be located close to the device (easily reached), and marked as a circuit breaker. The switch or circuit breaker to be used for power disconnect shall be certifi ed to IEC 60947-1 and IEC 60947-3, per IEC 61010-1, Clause 6.11.4.2. Overcurrent protection (rated > 10 A) is required for the power cable.
