VEGATRENN 142 Product Overview
VEGATRENN 142 is a high-performance isolation amplifier launched by VEGA, mainly used for isolation, conversion, and transmission of 4…20 mA signals in industrial process measurement. It can effectively suppress ground loops and electromagnetic interference, ensuring stability and accuracy of signals during long-distance transmission.
This instrument is widely used in chemical, petroleum, water treatment, and pharmaceutical industries, and is used in conjunction with sensors such as pressure, level, and temperature. This article provides the download of the VEGATRENN 142 Chinese manual and summarizes key technical information for the reference of engineering technicians and procurement personnel.
Main Functions and Features
- Signal isolation: Three-terminal isolation of input, output, and power supply, effectively eliminating ground loop interference.
- High-precision transmission: Typical accuracy ±0.1%, ensuring measurement signals are not distorted.
- Wide power supply range: Supports 20…253 V AC/DC wide voltage power supply, adapting to various on-site power sources.
- Compact design: Modular housing, supports DIN rail mounting, saving control cabinet space.
- Intrinsically safe: Optional explosion-proof version, suitable for hazardous areas.

Installation and Wiring Steps
- Power off: Before installation or wiring, ensure the power supply is disconnected.
- Rail mounting: Snap the VEGATRENN 142 onto a 35 mm DIN rail, ensuring the clip is locked.
- Input wiring: Connect the sensor signal wires to the input terminals, observing positive and negative polarity markings.
- Output wiring: Connect the output terminals to PLC/DCS or display instruments.
- Power wiring: Connect the 20…253 V AC/DC power supply according to the nameplate markings.
- Check and power on: After confirming correct wiring, power on and observe the indicator light status.
Commissioning and Common Issues
Commissioning Points
- Use a standard signal source to input 4 mA, 12 mA, and 20 mA, and check the corresponding output values.
- If the output deviation is large, check whether the supply voltage is within the allowable range.
- Ensure input and output cables are routed separately to avoid interference.
Common Troubleshooting
- No output: Check whether the power supply is normal and whether the fuse is blown.
- Output fluctuation: Check whether grounding is good and whether there are strong electromagnetic interference sources.
- Accuracy degradation: Confirm whether the sensor signal is normal and whether the terminals are loose.
