MODBUS-8PT-PT100 Thermal resistance model



Product overview

The module can measure 8 3-wire PT100 thermal resistance signals, and the module can be widely used in temperature measurement systems. Its output is 485 bus mode and MODBUS-RTU communication protocol, which is convenient for PLC and configuration software application.

Main parameter

Power supply voltage 9-28 VDC

Channel 8 PT100

Measuring range -50 ~ 300℃

Sampling rate 0.16S per channel,

8 channel cycle measurement Temperature resolution Temperature resolution 0.1 ° C

Operating temperature -20 ~ 70°C

Install

Standard DIN rail installation or screw installation calibration manual, simple operation communication interface RS-485 interface, two-wire communication speed 1200 ~ 115200bps can be set by software, default 9600 communication format can be set, default 8 data bit, 1 stop bit, None Verification station ID 1-247 The default value is 1

Temperature data format description: One temperature data contains 2 bytes, a total of 16 bits, is a 16-bit signed integer. When the highest bit is 1, it indicates that it is a negative number (ranging from -32768 to 32767) stored in complement mode. When reading the measured value /100, it is the actual temperature value. (When it is negative, the number is reduced by 1 and then reversed to the actual negative temperature value, for example, hexadecimal 88d5, 88D5-1 after 88D4,88D4 and then reversed to 772B, 772B represents the base 10 of 30507, so 88D5 represents the negative number of -30507, After dividing 100, it is 305.07 degrees, for the negative number expressed by the complement method, the computer will automatically convert, and the user only needs to express the number as a signed integer when reading the data in their own programming.
