Yokogawa Temperature Transmitter (YTA Series), Model: UD1CG3-004N-1AA-2SA-N/CN<br />
This is a head-mounted, two-wire temperature transmitter from Yokogawa's YTA series. It is designed for direct field mounting on a temperature sensor's connection head. This model is uniquely configured to accept a DC Voltage or Resistance signal input (0-5V DC) and convert it into a standardized 4-20 mA analog output signal, incorporating HART® 7 protocol for digital communication and configuration.
Key Technical Parameters Summary
Input Signal: 0 to 5V DC (Other voltage or resistance ranges are possible via configuration)
Output: 4-20 mA DC, 2-wire system, with HART® 7 protocol
Scaled Range (EU): 0 to 50 °C (The output is linear with this engineering value)
Power Supply: 12 to 42 V DC (standard loop power for 2-wire instruments)
Ambient Temperature: -50 to 85 °C (-58 to 185 °F)
Housing: Plastic (ABS)
Electrical Entry: Two M20 x 1.5 (Metric conduit connection)
Display: None
Safety Approvals (Primary):
ATEX/IECEx/UKCA: Ex ia IIC T6 Ga (Intrinsic Safety) / Ex nA IIC T6 Gc (Non-Incendive)
Mounting: Head-mounted Typical Applications:
This configuration is used for interfacing with devices that don't have a standard 4-20 mA output, such as:
Converting signals from load cells (weight) or pressure transducers into a 4-20 mA loop.
Interfacing with third-party equipment that only has a voltage output.
Adding HART capability to an existing voltage-based signal path.
Providing intrinsic safety isolation for a voltage signal entering a hazardous area.
