Signal input, CPU, power input andRS485 communication electrical signals are isolated from each other, effectively suppressing all kinds of serial mode and common mode interference, ensuring the accuracy of data, but also ensuring the reliable work of the module.
MB8ARTThe module is mainly used for temperature acquisition and application of various analog input signal types. It can be widely used in iron and steel smelting, metal heat treatment, chemical industry, metallurgy, glass processing, injection temperature control, tobacco, medicine, automation equipment and so on.
- Characteristic
8Road mixed signal input (thermocouple, platinum resistance and analog).The input signal types of channels can be set according to their needs..
The thermocouple, thermal resistance andFour-20mA input have the function of detection and break detection, which is convenient for on-site debugging and maintenance.
Full differential input, and each channel is isolated from each other.
High precision signal acquisition: high precisionTwo4 bit AD and voltage reference, voltage reference temperature coefficient 10PPM/ centigrade.
Independent high precision cold end compensation with accuracy of + 0.5 C.
Safety: signal collection, signal output, power supply, RS485 communication and electrical signals are isolated from each other.
Adopting the standard Modbus-RTU protocol, the RS485 communication signal output interface adopts over voltage and over current double protection.
The input signal type and communication format can be set by software.
Power input polarity protection and overvoltage protection.
