Technical Specification
| Design | Based on high speed 32 bit Microcontroller and 16 bit ADC |
| Analog / Digital Signal Input | 1) Thermocouple: J, K, E, T, B, R, S types (any one user selectable) RTD: Pt-100 2 or 3 wire, or Variable Resistance (Any one to specify) Voltage: 0-1V,0-5V,1-5V,0-10V, +/-10V, Current: 0-20mA, 4-20mA, +/-25mA 2) Digital Serial Input: RS-485 over MODBUS RTU protocol. 3) Digital Input: NPN / PNP or potential free contact. |
| Factory Set Input | User may specify at the time of placing order. |
| Display | 4 digit – 4” seven segment red LED display (DPI-4000-M) 4 digit – 1” seven segment red LED display for SET Point / for Unit display (optional) |
| Display Range | Full positive range of thermocouple or Pt-100 and -1999 to 9999 counts for others - user scalable. |
| Decimal Point | User settable through keyboard |
| Calibration Range | User can calibrate or scale the desired range as per requirement using front panel 4 push buttons. |
| Resolution | 1 °C for thermocouple input and 0.1 °C for Pt-100 input. For other process input as per the user requirement. 1 count, 0.1 count, 0.01 count or 0.001 count (user selectable – through front panel push buttons – only for process inputs) |
| Accuracy | +/-0.1% of the specified range for Process Input +/-0.1 °C or +/-1oC for Input from Temperature sensors (Software linearized for T/C and Pt-100 input) |
