Siemens 6ES7288 series module 18 / 09

Siemens, as a leading enterprise in the field of industrial automation, plays a significant role in industrial automation control systems with its 6ES7288 series modules. 

 

I. Overview of Siemens 6ES7288 Series

The Siemens 6ES7288 series modules are programmable logic controller (PLC) expansion modules specifically designed for industrial automation. They are widely used in various automation control systems. This series encompasses various types of modules, including digital input/output modules, analog input/output modules, communication modules, and more, catering to diverse control requirements.

 

 

II. Specific Parameters and Functions

1.Digital Input Module (Example: 6ES7288-2DE08-0AA0)

  • Model: 6ES7288-2DE08-0AA0
  • Function: This module is a digital input module that supports 8 x 24V DC input points, suitable for receiving switching signals from sensors, buttons, and other devices.
  • Parameters:
  1. Number of Input Points: 8
  2. Rated Voltage: 24V DC
  3. Logic 1 Signal (Min.): 15 V DC at 2.5 mA
  4. Logic 0 Signal (Max.): 5 V DC at 1 mA
  5. Filtering Time: 0.2, 0.4, 0.8, 1.6, 3.2, 6.4, and 12.8 ms (selectable, 4 in a group)
  6. Maximum Cable Length: 500 meters for shielded cables, 300 meters for unshielded cables

 

2.Digital Output Modules

The Siemens 6ES7288 series also includes various digital output modules, such as 6ES7288-2DR08-0AA0 (8 relay outputs) and 6ES7288-2DT08-0AA0 (8 x 24V DC outputs). These modules are used to control external devices like motors and indicator lights.

 

3.Analog Input/Output Modules

Analog modules like 6ES7288-3AE04-0AA0 (4 inputs) and 6ES7288-3AQ02-0AA0 (2 outputs) handle continuously varying physical quantities such as temperature and pressure. They convert analog signals into digital signals for PLC processing or convert PLC digital signals into analog signals for output to external devices.

 

III. Application Examples

Example 1: Automated Production Line Control

On an automated production line, Siemens 6ES7288 series modules are extensively utilized for various control tasks. For instance, the 6ES7288-2DE08-0AA0 digital input module receives switching signals from sensors and buttons, such as material arrival signals and emergency stop button signals. After processing these signals through the PLC, the 6ES7288-2DR08-0AA0 relay output module controls the start/stop and material transportation actions of the production line.

 

Example 2: Temperature Control System

In a temperature control system, the Siemens 6ES7288-3AE04-0AA0 analog input module receives analog signals from temperature sensors, such as 4-20mA current signals. The PLC processes these signals internally to calculate the current temperature value and compares it with the setpoint. If the temperature deviates from the setpoint, the PLC controls the 6ES7288-3AQ02-0AA0 analog output module to output corresponding control signals, adjusting heating or cooling equipment to maintain the temperature within the desired range.
