Features
Auto-tuning (AT)-
*RAMP and Soak
- Build in 1 segment of RAMP and SOAK function.
*Approval and Free Power
- All WT models get CE approval. Operate on any voltage from AC 85~265V at 50/60Hz. DC24V is also available.(*Optional Function)
*High Accuracy
- Input with 14 bit A/D resolution, 0.2% accuracy of FS. Build in Auto Zero- Auto Span function to keep good accuracy.
*Data Lock Function
- All parameters are separated in 3 operation levels. Each parameter can be hidden or locked to prevent unauthorized changes.
*Modbus Communication (Optional Function)
- WT series sport both Modbus RTU and MODBUS ASCII protocol.
* Heater Break Alarm (HBA)(Optional Function)
- Heater current flowing through CT can be displayed on controller.
