Microcontroller Based Temperature Scanners - 8 CHANNEL

Product Specification :

Model wise descriptions :

Model Model Description     (XX = No. of channel ) Size (WxHxD) (mm.)
7.4 MSI-804 2 to 8 Channel Temperature/Process Scanner with user selectable input. 96 X 96 X 160
7.5 MSI-804-S
2 to 8 Channel Temperature/Process Scanner with user selectable input and RS485 interface 96 X 96 X 160

Description :

Libratherm offers Microcontroller based Temperature / Process Scanner Model MSI-804 which is designed for continuous, simultaneous and very accurate monitoring of temperature or process values at maximum 8 different locations.

The Model accepts universal input of standard thermocouples or RTD(Pt-100)/3 wire sensors and voltage or current signals. The type of input for each channel is user selectable from the keyboard, i.e. all 8 channels can be selected for different type of input. MSI-804 offers 5 digit display having the range of 0 to 20000 counts or -10000 to +10000 counts. Such wide display range makes it possible to display the temperature or process value with the highest degree of accuracy and resolution. For example, using R type thermocouple the temperature can be displayed with 0.1oC resolution from 0.0 to 1768.0oC. Similarly, any other process value can be precisely displayed with desired resolution within the specified range.

Other hardware features includes, 2 nos. of common high/low relay outputs, 16 nos. of relay drivers as high and low alarm for all 8 channels and 2 nos. of RS485 serial port on Modbus RTU protocol for serial interface to any Master device. The respective front panel LEDs shows the status of all the outputs. Standard features include programmable SCAN rate, channel HOLD and SKIP facility with manual increment of the channel number using front panel membrane keyboard.
