The WERT.I 8000 Series is a DIN-rail signal conditioner, splitter and isolator. It provides galvanic isolation and conversion of standard process current or voltage signals for connection to SCADA or PLC systems, while helping eliminate ground loops and reduce the effects of surges, transients and noise.
Key Features
- Isolation and conversion of standard DC current and voltage signals
- One-input configurations with one or two outputs
- Isolation between input, output and power supply
- Supports measurement of floating signals
- Compact DIN-rail design
