The EL2809 module is equipped with eight digital inputs, which can be used to connect various sensors and signals in industrial applications. The inputs are galvanically isolated and can handle both 24V DC and 120V AC signals. The module supports both sinking and sourcing input types, allowing flexibility in connecting different types of devices.

The EL2809 module communicates with the EtherCAT master device, such as a Beckhoff programmable logic controller (PLC), over an EtherCAT bus. This allows for fast and precise data transfer between the module and the control system, ensuring real-time monitoring and control of the connected inputs.

24V differential inputs: These inputs are designed for differential signal inputs, which can provide better noise immunity and signal integrity in certain applications.

The EL5101 digital input module is typically used in industrial automation and control systems, where monitoring and control of digital signals are required. It can be integrated with other Beckhoff EtherCAT modules to create a distributed control system.
