VEGA TRENN 142 VEGATRENN 142 Separator for 4 … 20 mA/HART sensors
$150.00
The VEGATRENN 142 Separator is a dual-channel, active signal isolator designed for 4–20 mA/HART sensors. It provides reliable galvanic isolation, signal transmission, and intrinsically safe power supply in hazardous areas. This makes it ideal for connecting Ex-approved sensors to control systems.
In addition, the device supports full bidirectional HART communication, so you can access and configure sensors without signal loss. Its separate power supply design ensures stable and accurate signal transmission in demanding environments.
Not Recommended For:
• Applications requiring passive isolators without power supply
• Single-channel, low-cost installations
Selection Notes
• Signal Type: The VEGATRENN 142 supports 2 × 4–20 mA inputs and outputs with full HART transparency. Confirm compatibility with your field instruments and control system.
• Channel Requirement: This is a dual-channel device. It is ideal for applications where two signals must be isolated and transmitted simultaneously.
• Power Supply: The device requires an external supply (20.4–34.1 V DC) to power both the unit and connected sensors.
• Hazardous Area Use: Designed for intrinsically safe applications, it ensures safe operation in hazardous (Ex) zones.
• Installation Method: Supports DIN rail mounting with detachable, coded terminals for quick wiring and maintenance.
Why Choose the VEGATRENN 142
• Dual-Channel Signal Isolation
The VEGATRENN 142 handles two independent signal channels at the same time. Therefore, it improves efficiency and reduces cabinet space compared to single-channel devices.
• Active Isolation with Power Supply
Unlike passive separators, this unit provides an intrinsically safe power supply to connected sensors. As a result, signal transmission remains stable and reliable.
• Full HART Transparency
It supports bidirectional HART communication. You can configure, monitor, and diagnose sensors without disconnecting the loop.
• Reliable Performance in Hazardous Areas
The device ensures galvanic isolation between hazardous and safe areas. This protects equipment and improves system safety in Ex environments.
• Fast Installation and Maintenance
DIN rail mounting and removable coded terminals simplify installation. In addition, maintenance becomes faster and less error-prone.
