The Honon-900C30-0460 is an analog input module used in Honeywell process control systems.

Honeywell is a company engaged in the development, production and sales of automated control systems, instrumentation, and security products, and its products are widely used in petroleum, chemical, power, pharmaceutical, food, beverage, agriculture and other fields. Among them, Honeywell Process control System is one of the company's important products, it is a computer or microprocessor based automatic control system, can be used to monitor, control and optimize various parameters in the industrial production process. In the system, the analog input module is an important part, HonON-900C30-0460 is used to convert the continuously changing analog signals into discrete digital signals for computer or microprocessor processing and analysis.

Honon-900c30-0460 analog input module is a device that collects analog signals from remote field to computer. It uses RS-485 bus as a data communication line to provide analog to 485 function, which can simultaneously input analog signals to the module and transmit them to the computer through RS-485 bus. As the RS-485 interface is used as the communication interface, it can combine multiple modules to transmit more analog signals, and can be distributed on the 485 line, using the address code to distinguish, and can directly access the configuration software of MODBUS RTU protocol.

The working principle of the HonON-900C30-0460 analog acquisition module is to convert the continuously changing analog signal into discrete digital signal by using the analog-to-digital converter (ADC).

The HonON-900C30-0460 analog-to-digital converter samples the analog signal according to a certain sampling frequency and converts the sampled value to digital form. There are two common analog-to-digital converters: successive approximation type and Delta-sigma type. The successive approximation analog-to-digital converter compares the analog signal with the reference voltage in a step-by-step approach until it reaches the threshold.
