AB91-1 HESG437479R1 HESG437899 Analog module is an important part of industrial automation and control system, mainly includes analog input module, analog output module and analog input/output module.

The main function of the AB91-1 HESG437479R1 HESG437899 analog input module (also known as A/D module) is to convert analog signals collected from various industrial field sensors into digital quantities that the CPU can recognize as received. These sensor data may include analog values of voltage, current, thermal resistance, thermocouple, temperature, etc. These analog signals are collected and processed inside the module, and then transmitted to the intelligent module of the computer through the bus.

The AB91-1 HESG437479R1 HESG437899 analog input/output module has the functions of both modules, which can collect analog signals and convert them into digital ones, and can also convert digital ones into analog outputs.

In addition, the AB91-1 HESG437479R1 HESG437899 analog module usually supports a variety of acquisition ranges, and can be interlinked with various configuration software, with display functions, remote management functions, etc. For example, some modules support remote instrument setup and program upgrade through GPRS transmission equipment, or provide analog to 485 function through RS-485 bus as a data communication line, and can transmit more analog signals through multiple modules.
