YOKOGAWA Juxta VJA1 Signal Conditioner
YOKOGAWA Juxta VJA1 Signal Conditioner
INTRODUCTION
The VJA1 is a compact, plug-in type distributor that is used in combination with a two-wire type transmitter to convert the transmitter’s 4 to 20 mA DC signals into isolated DC current or DC voltage signals.
• HART communication: VJA1/H (option code /H) Bi-directional relay of HART communication signals is possible while the field devices and the higher-level device are isolated from each other

Product Overview
Brand and Series: YOKOGAWA's (Yokogawa Electric) Juxta VJ series signal converters, specifically the VJA1.
Features: Compact embedded design, microprocessor-based high performance (multifunction type), making it the choice for almost any application.
Main Functions and Features
Input and output types:
Input: receives a variety of signals such as thermocouples, RTDs or mVs as required.
Output:
Analogue output: such as 4-20mA DC, 0-10mV DC, 2-10mA DC and many other current and voltage signals.
Optional outputs: upper/lower limit alarm relay output or RS-485 Modbus communication as optional two outputs.
Design Advantages:
Compact design: space-saving, external dimensions of approximately 76 H x 29.5 W x 124.5 D (mm).
Two Isolated Outputs: Two isolated current or voltage (pulse) outputs are optional to ensure the reliability and safety of signal transmission.
Communication function: Some models support Modbus (RS-485) communication function, which is convenient for data exchange with various industrial automation equipment and systems.
Alarm Output: Some models support optional upper/lower limit relay alarm outputs for monitoring and sending alarm signals.
Configuration and Setting:
Setting and modification of various parameters (e.g. input range and arithmetic procedure) can be completed through PC (e.g. VJ77) or hand-held terminal (e.g. JHT200), which is convenient for users to configure flexibly according to actual needs.
