Siemens 6ES5895-4SA21 Analog I/O Module

Product manual:

Siemens 6ES5895-4SA21 is an analog input/output (I/O) module belonging to the Siemens S5 series PLC system. Analog I/O modules are used to process analog signals from field devices, such as voltage or current signals emitted by sensors and actuators, which typically represent physical parameters such as temperature, pressure, liquid level, etc.
Main features:
Model: 6ES5895-4SA21
Series: Siemens S5 Series
Type: Analog I/O Module
Input/Output Type: Supports processing analog signals (such as voltage or current), converting analog signals from external devices into digital signals that can be processed by the PLC system, or converting digital signals processed by the PLC into analog signals and outputting them to field devices.
Number of channels: It may have multiple analog input and/or output channels, and the specific number of channels depends on the module design.
Main functions:
Analog input: Accept analog signals from external devices such as sensors and transmitters, such as voltage or current, and convert them into digital signals for PLC use.
Analog output: Convert digital control signals generated by PLC into analog signals to control actuators or other devices.
Signal processing: capable of processing analog signals in different ranges, such as 0-10V voltage signals or 4-20mA current signals.
Application areas:
Industrial automation: widely used in the field of industrial control for measuring and controlling physical quantities such as temperature, pressure, flow rate, etc. These parameters are usually transmitted through analog signals.
Process control: Suitable for industries such as chemical, petroleum, and food processing that require precise control of physical parameters.
Building automation: used for HVAC systems or other automation systems that require processing of analog signals.
Advantages:
Multifunctionality: Supports input and output of analog signals, capable of processing signals from multiple devices simultaneously.
High precision: Ensuring precise acquisition and output of analog signals helps achieve high-precision control.
Modular design: seamlessly integrated with other modules in the S5 series, easy to install and maintain.
