Application
- Carry thermocouple or RTD signals over long distances without noise and loss of accuracy.
- Eliminates use of costly compensating cable.
- Useful for converting other mV/Ohms signal to equivalent 4-20mA loop.
Technical Specification
| Parameters | Description |
|---|---|
| Input | Thermocouple, RTD (Pt-100) or resistance signal from displacement, position or level sensor |
| Range | Subject to specified input (Refer ordering information) |
| Output | (4-20) mA, two wire and loop powered |
| (calibrated linearly to the input signal). | |
| Accuracy | ± 0.5 % to +/- 1% of the calibrated range or better including linearity, Hysterisis, and compensation error. |
| Calibration | On site using ZERO / SPAN presets (user settable using a small screw driver) |
| Zero Adjustment: +/-25% of the range (20 Turns). | |
| Span Adjustment: +/- 25% of the range (20 Turns). | |
| Loop supply (Vs) | (12 to 36) VDC |
| Loop Status | The built in Red LED indicates the continuity status of the loop. |
| LED will not glow if the current loop is broken. | |
| Loop Resistance | 600 Ohms @ 24VDC (loop supply dependent). |
| Max. Load Resistance | RL Max = (Vs-12V) / 20 mA. |
| Isolation | Input and Output are Galvanically isolated (> 1KV) for isolated models |
| Burn Out Detection | The output shall saturate > 20mA (max. 25mA @ 24VDC loop supply) |
| Operating Temp. | 10 °C - 70 °C |
| Sizes | 44 Dia. X 26 mm (H) |
