Ultra Compact Size |
Ultra low behind the panel depth of 28mm enables the control panels to be made very compact and elegant. The cost of the panels will also be significantly lower.
Accurate |
Software linearized using multiple NIST inverse polynomials and Steinhart & Hart equation involving floating point arithmetic ensures a very high accuracy.
Field configuration |
Completely Field selectable. Important parameters like sensor selection, Heat/Cool mode, Hyssteresis etc., can be selected in the field. There are no jumpers or presets.
Wide Input Powersupply |
SMPS Powersupply designed to withstand the Indian Industrial Power conditions. This rugged 90-270VAC/DC powersupply, ensures flowless functioning under extreme coltage conditions.
Reliable & State-of-the-art |
Advance Single Chip (DSP) based design that uses a fraction of the component usually present in temperature controllers. Lower component count makes this product much more reliable.
Reliable |
No presets and jumperless design.
Adjustable Persistance time |
To prevent fast state change of the O/P relay, two settings are provided.'ON Persistance Time' and 'OFF Persistance Time'.
Once the controller decides to put the output relay ON then the relay remains ON for at least the time set in the 'ON Persistance time' parameter, regardless of the change in the process temperature.
Similarly the 'OFF Persistance Time' parameter controls the relay OFF time.
This feature is specially useful in applications like compressors and gas fired ovens.
Parametre locking |
Configiration locks to prevent unauthorized tampering.
