NTC to 485 thermistor

　　1. Read analog input module data command

　　Description: Read back the temperature data of the thermal resistance from the module, the data is the actual temperature value. If the data is -888.88, it means the thermistor is disconnected,

　　If the data is 888.88, it means the thermistor is shorted.

　　Command format: #01

　　Parameter description: # delimiter.

　　01 Module address, the value range is 00～FF (hexadecimal). The factory address is 01, which is converted to hexadecimal for the ASCII code of each character. For example, the address 01 is changed to 30H and 31H in hexadecimal.

　　Response format: >(data)(cr) command is valid.

　　?AA(cr) Command invalid or illegal operation or channel is closed.

　　Parameter description: > Delimiter.

　　(data) represents the data read back. The data format is temperature value.

　　(cr) terminator, the upper computer enter key (0DH).

　　Other instructions: If the syntax error or communication error or the address does not exist, the module will not respond.

　　Application example: User command (character format) #01

　　(hexadecimal format) 233031

　　Module response (character format) >+018.00 (cr)

　　(hexadecimal format): 3E2B3031382E30300D

　　Description: The input on the address 01H module is: +018.00

　　The multi-channel signal acquisition between the sensor and the host is used to detect the temperature signal. IBF126 series products can be used in RS-485 bus industrial automation control system, temperature signal measurement, monitoring and control, etc.

　　Products include power isolation, signal isolation, linearization, A/D conversion and RS-485 serial communication. Each serial port can connect up to 255 IBF126 series modules. The communication method adopts ASCII code communication protocol or MODBUS RTU communication protocol. The address and baud rate can be set by code. It can be hung on the same RS-485 bus with other manufacturers' control modules. Ease of computer programming.

　　● Resistor isolation conversion RS-485 output such as NTC10K/NTC20K

　　● The internal MCU performs linear processing on the input resistance value

　　● Using 12-bit AD converter, the measurement accuracy is better than 0.1%

　　● Through the RS-485 interface can program-control the calibration module accuracy

　　● Isolation withstand voltage 1000VDC between signal input/output

　　● Wide power supply range: 8 ~ 32VDC

　　● High reliability, convenient programming and easy application

　　● Standard DIN35 rail installation, convenient for centralized wiring

　　● User can programmatically set module address, baud rate, etc.

　　● Support Modbus RTU communication protocol, automatic identification protocol

　　● Industrial flame retardant enclosure, RS485 port surge protection
