Description of Microprocessor indicator
Microprocessor based indicator in both 48x48 (1/16 DIN) formats manufactured with SMT. The instrument have a lexan membrane faceplate (guaranteed to IP65) which has 3 keys, a 4-digit display. The input signal can be selected from a wide range of sensors:
- Thermocouples of type J, K, R, S, T, B, E, N, L GOST, U, G, D, C
- Resistance thermometers Pt100, JPt100, 2 / 3 wire
- PTC and NTC themistors
- Linear inputs 0 to 60/12 to 60mV, 0 to 20/4 to 20mA, 0 to 10/2 to 10/0 to 5/1 to 5/0 to 1/0, 2 to1V
The selection is made using the faceplate keys and correct input contact.
No external shunt or adapter is required.
The programming of the instrument is made easy by grouping the parameters in function blocks and by a simplified data entry menu. The configuration can be simplified even further using the PC programming kit made up of a connection cable and
a menu guide program that runs under windows.
A configurable personal software protection code (password protection) can be used to restrict the levels of editing and displaying the configuration parameters.
