Features
- Interfaces with industrial standard PT-100 temperature sensors.
- Six programmable overlapping temp. ranges between -50 -300°C.
- Programmable for over and under temperature.
- Temperature level adjustment on calibrated scale 0-100%.
- High repetitive accuracy.
- Programmable inversion of relay output for fail-to-safe operation.
- 0 to 1mA proportional output for each temperature range.
- Proportional output is limited to 1,2 mA to protect analogue instruments.
- Latching on under-temperature or 0ver-temperature (programmable).
- 10A SPDT relay output.
