Z7127 Analog input module is a device that can collect analog signals from remote field to computer. It usually uses the RS-485 bus as a data communication line, providing analog to 485 function, which can simultaneously input analog to the module and transmit it to the computer through the RS-485 bus. This module can combine multiple modules to transmit more analog signals, and can be distributed on 485 lines, using address code to distinguish, and can directly access the configuration software of MODBUS RTU protocol.

The function of the Z7127 analog input module is to collect analog signals, such as voltage, current, temperature and other values. In the industrial automation measurement and control system, the analog input module can measure the 4 ~ 20mA, 0-20mA, 0-10V or 0 ~ 5V signals output by the transmitter such as pressure, temperature and electricity, and the thermal resistance temperature of various models such as PT100.

Z7127 analog input module can be used to solve PLC, motion controller analog input problems, such as current detection, voltage detection, temperature detection, etc. The principle is that when the interference is relatively large, C1627, C1628, C624, C331 four capacitors can be used to form a two-stage filter circuit to improve the circuit design. In addition, it also supports a variety of acquisition ranges, various configuration software docking and other technical parameters.

The Z7127 analog input module is used in a wide range of applications, such as power monitoring systems, smart home control systems, medical equipment control systems and other fields.
