YOKOGAWA VJU7-027-UAA0

Product Overview

The YOKOGAWA VJU7-027-UAA0 is a precision universal temperature converter from the JUXTA VJ Series, manufactured by Yokogawa Electric Corporation. This plug-in type signal conditioner converts thermocouple, RTD, or millivolt (mV) input signals into isolated DC voltage or current output signals, providing reliable and accurate temperature measurement for industrial automation systems. Based on a microprocessor-driven design, the VJU7 series integrates seamlessly with DCS, PLC, and SCADA architectures, serving process industries such as chemical, petrochemical, power generation, and HVAC applications-11.

Model Number Breakdown: YOKOGAWA VJU7-027-UAA0

The suffix code provides a complete product identification:

Code Segment	Interpretation
VJU7	Universal temperature converter (thermocouple, RTD, mV input)-21
-0	Fixed designation code
2	Output configuration: Isolated dual-output type-12
7	Power supply: 15–30 V DC (operating range: 12–36 V DC)-16
–	Separator
U	Input signal: Universal (thermocouple / RTD / mV)-12
A	Output-1 signal: 4–20 mA DC
A	Output-2 signal: 4–20 mA DC-12
0	Fixed code (always 0)

The VJU7-027-UAA0 therefore represents a dual-output, 15–30 V DC powered universal temperature converter configured with 4–20 mA DC linear output on both channels.
