DESCRIPTION
The FlexVu ® Model UD10 is recommended for applications that require a gas
detector with digital readout of detected gas levels as well as analog 4–20
mA output with HART, relay contacts, and Modbus RS485. The UD10 is
designed for use with Det‑Tronics gas detectors such as GT3000, PIR9400,
PIRECL, PIRECL CO 2 , C706x*, CTX10/CGS, CGS**, ATX10/AV10, PIRDUCT,
or LS2000, as well as generic linear 4–20 mA sensors. The display unit
is designed and approved as a “stand alone” device and performs all the
functions of a gas controller.
Gas concentration and unit of measurement are indicated on a digital display.
The display unit provides a linear isolated/non-isolated 4–20 mA DC output
signal (with HART) that corresponds to the detected gas concentration.
All electronics are enclosed in an explosion-proof aluminum or stainless steel
housing. The display unit is used with a single detector that may be either
coupled directly to the UD10, or remotely located using a sensor termination
box. The UD10 features non-intrusive calibration. A magnet is used to perform
calibration as well as to navigate the UD10’s internal menu.
The UD10 can be used with various 4–20 mA gas detection devices,
with or without HART. The unit provides display, output, and control
capabilities for the gas detector.
The UD10 utilizes the following I/O:
- Signal Inputs: 4–20 mA loop from the sensing device
- User Inputs: Magnetic switches (4) on the display panel HART communication
- Signal Outputs: 4–20 mA output loop with HART, Modbus RS485, Three alarm relays and one fault relay
- Visible Outputs: Backlit LCD display, ART slave interface via HART Communicator
