It can be used to monitor the state of various devices, sensors, or switches in an automated system.
Here are some key features of the Beckhoff EL4004 module:
Digital Inputs: The EL4004 module offers four isolated digital inputs. These inputs can handle both 24 V DC and 5 V DC signals, making it compatible with a wide range of devices.
Isolation: Each input channel of the EL4004 module is individually isolated, providing protection against electrical interference and ensuring reliable operation.
Input Signal Filtering: The module provides configurable input signal filtering to help eliminate noise and provide stable input readings.
Diagnostic LEDs: The EL4004 module includes diagnostic LEDs for each input channel, allowing for easy status monitoring during operation.
Connection: The module is connected to the Beckhoff PLC system via a standard Beckhoff Bus Terminal system, which provides a convenient and modular approach to expand the I/O capabilities of the PLC.
Configuration and Programming: The EL4004 module can be easily integrated and configured within the TwinCAT programming environment, which is a software platform provided by Beckhoff for PLC programming and configuration.
