MICROCONTROLLER BASED TEMPERATURE SCANNER

Category: Temperature Scanners / Digital Indicators & Controllers

Description

Function :
Microcontroller based Temperature Scanner is designed for fast and accurate measurement and control of the Process Temperature. The Scanner monitors & displays the Process Temperature as well as does ON / OFF Control according to the Programmed Set Point.

Microcontroller based design.
Input from RTD (PT100) or Thermocouple (J type OR K type).
Standard channels available are 8 or 16
7-Segment LED Display : • 4 Digit for displaying data. • 2 Digit, for Process Parameters. • 1 or 2 Digits, for indicating channel No.
LEDs for indication of the process control action with Relay output Contacts.
Fully Programmable through Membrane Keyboard.
Flexible input channel grouping facility.
Channel skipping facility.
Programmable Lo & Hi set points.
Programmable display update time.
Programmable Relay Logic & LED Logic.
Auto & Manual mode of operation.
Programmable Auto or Manual Reset facility.
Password protected Program Mode, calibration Mode.
Software Calibration facility for input and 4-20 mA output.
Sensor Open, Sensor Short indication.

Optional Features

System OK status.
4-20 mA current output proportional to max. Temp in corresponding group or Temperature of individual channel.
4-20 mA Current Output corresponding to channel No.
RS-232 or RS-485 communication compatible to MODBUS RTU protocol.
PROFIBUS Connectivity (DP V0).
