VEGA TRENN 151 VEGATRENN 151 Separator for 4 … 20 mA sensors
$150.00
The VEGATRENN 151 Separator is a compact, single-channel signal isolator designed for 4–20 mA sensors. It provides reliable galvanic isolation and safe signal transmission in hazardous and non-hazardous environments. This makes it ideal for connecting Ex-approved sensors to control systems without intrinsic safety approval.
The device supports bidirectional HART communication, allowing full access to sensor configuration. In addition, it requires no separate power supply, which simplifies installation and reduces wiring effort.
Not Recommended For:
• Applications requiring multi-channel signal isolation
• Systems needing active signal amplification
Selection Notes
• Signal Type: The VEGATRENN 151 supports 1 × 4–20 mA input/output with HART transmission. Confirm compatibility with your sensor and control system.
• Application Area: It is ideal for hazardous areas (Ex zones) where safe signal isolation is required between field devices and control systems.
• Channel Requirement: This is a single-channel, passive device. If you need multiple channels, consider other models like VEGATRENN 152.
• Installation Method: The unit supports DIN rail mounting with removable terminals, ensuring quick and easy installation.
• Environment: Suitable for ambient temperatures from -20 to +60°C. Ensure your installation environment falls within this range.
Why Choose the VEGATRENN 151
