D201832 microcontroller Analog input module

D201832 Industrial MCU is a microcontroller suitable for industrial control scenarios. Compared with consumer MCU,

industrial MCU indicators are more stringent, and the operating temperature range of industrial MCU is-40°~+85°C, service life of

5-10 years, MCU chip is the core components in the field of industrial control, used inindustrial robots, stepping motors, robot arms,

instruments, industrial motors, industryDiesel engine, ventilator system, energy gateway and other products,MCU

chip plays a complex, high-speed calculation, variable speed control, signal collection, data transmission and so on.

The function of the D201832 switching input module is to turn various switching signals into the T1 standard

signals of the CPU, which can be converted into DC input modules and AC input modules according to the input power type,

and the input signals are converted into TTL(5V) standard signals through voltage division, current limiting,

filtering and photoelectric coupling.The function of the D201832 analog input module is to convert the continuously

changing analog signals such as temperature, flow, current, voltage, etc. into several digital signals that the CPU can process.

The analog input circuit is generally composed of op amp conversion, mode conversion (A/D), photoelectric isolation, etc.
