0-75mv/0-100mv to rs485/232 communication interface Modbus RTU acquisition module ibf8

Function introduction ：

IBF8 Signal isolation acquisition module , It can be used to measure eight voltage or current signals .

1. Analog signal input

24 Bit acquisition accuracy ,8 Analog signal input . All signal input ranges of the product have been calibrated before delivery . When use , Users can also easily program and calibrate themselves . Please refer to product selection for specific current or voltage input range .

1. Communications agreement

communication interface ： 1 Road standard RS-485 A communication interface or 1 Road standard RS-232 communication interface , When ordering, please indicate .

Communication protocol ： Two protocols are supported , Command set defined character protocol and MODBUS  RTU Communication protocol . The module automatically recognizes the communication protocol , Can be realized with a variety of brands PLC、RTU Or computer monitoring system for network communication .

data format ：10 position .1 Bit start bit ,8 Digit bit ,1 Bit stop bit .

postal address （0～255） And baud rate （2400、4800、9600、19200、38400、57600 、115200bps） Can be set ; The communication network can be as long as 1200 rice , Connect by twisted pair shielded cable .

High anti-interference design of communication interface ,±15KV ESD Protect , Communication response time is less than 100mS.       

1. anti-interference

Check sum can be set as required . There is a transient suppression diode inside the module , It can effectively suppress all kinds of surge pulse , Protection module , Internal digital filtering , It can also suppress the power frequency interference from the power grid .

IBF8 The product realizes the signal acquisition between the sensor and the host , Used to detect analog signals .IBF8 Series products can be used in RS-232/485 Bus industrial automation control system ,4-20mA / 0-5V Signal measurement 、 Monitoring and control ,0-75mV,0-100mV And so on small signal measurement and industrial field signal isolation and long line transmission and so on .

Products include power isolation , Signal isolation 、 Linearization ,A/D Conversion and RS-485 serial communication . Each serial port can be connected to at most 255 only IBF8 Series modules , Communication mode adopted ASCII A code communication protocol or MODBUS RTU Communication protocol , Baud rate can be set by code , It can be hung in the same place with the control module of other manufacturers RS-485 On the bus , Easy to program .

IBF8 The series of products are based on the intelligent monitoring and control system of single chip microcomputer , All user set calibration values , Address , Baud rate , data format , Configuration information such as checksums and status is stored in nonvolatile memory EEPROM in .

IBF8 The series products are designed according to industrial standards 、 manufacture , Signal input / Isolation between outputs , affordable 3000VDC Isolation voltage , Strong anti-interference ability , High reliability . Operating temperature range - 45℃～+85℃.
