The AS-J890-102 analog input/output module is an intelligent module mainly used to collect analog signals from remote sites to the computer and transmit them to the computer through the 485 bus. This module uses RS-485 bus as the data communication line, providing the function of converting analog signals to 485. It can simultaneously input analog signals to the module and transmit them to the computer through the bus. Due to the use of RS-485 interface as the communication interface, this module can combine multiple modules to transmit more analog signals, and can be configured dispersedly on the 485 line. It uses address codes for differentiation and can directly connect to the MODBUS RTU protocol configuration software. The analog input module can collect analog values such as voltage, current, thermocouple, thermal resistance, temperature, etc., and transmit them to the computer through the 485 bus. The main function of the analog output module is actually to convert the input digital signal into digital analog, and output adjustable continuous voltage, current, and signal. For example, in the TV control block, for controlling various analog signals, taking sound as an example, first input the pulse digital signal emitted by the remote control or button scan into the control block, and after the analog-to-digital conversion of the analog output module, output a continuous voltage signal that can change with the input signal. Then, use this signal to control the sound channel, thereby controlling the volume, brightness, and contrast.
