Overview
The Eurotherm WV418 RTD is part of the Ultra Slim Pak II line of isolating signal conditioners from Action Instruments, a Eurotherm brand. The Ultra SlimPak II is an isolating signal conditioner line with greater accuracy and better stability than virtually any other signal conditioners on the market today. The WV418-2000.V1 is an Isolating Signal Conditioner with an isolated DC voltage or current output. This compact, DIN-rail mountable design is engineered for process temperature monitoring and signal isolation in demanding industrial environments.
Key Features
- Supports 2-wire, 3-wire or 4-wire Pt100 RTDs with alphas of either 0.00385 or 0.00392, as well as Cu10.
- Outputs include 0 to 10V, 0 to 20mA and 4 to 20mA.
- Ranges are DIP switch selectable or (optionally) PC programmable.
- Features Smart Power, which eliminates wasted power for low loop resistance loads in the current output mode.
- Features removable terminals for easy service.
- Built In Web Browser with Email and Logging Capability when connected via optional WVC16 Ethernet interface
Technical Specifications
The WV418 is configured for RTD temperature input with multiple output options. Maximum output is 0–10V DC or 0–20mA, with a 5-year warranty. Configured via DIP switches and push-button calibration. This device provides isolated signal conditioning suitable for integration with PLCs, DAQs, and analog input modules across temperature-monitoring systems.
Typical Applications
- Industrial process temperature monitoring and control
- Sensor isolation in multi-loop plant systems
- RTD input conversion to standard 4–20mA or 0–10V signals
- Integration with legacy and modern control systems
- Temperature data logging via optional Ethernet connectivity
