VEGA TRENN 142 VEGATRENN 142 Separator for 4 … 20 mA/HART sensors

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.
