The Beckhoff EL1852 EtherCAT Terminal is a multifunctional I/O module that combines both 8 digital inputs and 8 digital outputs in a single, compact housing. Operating at 24 V DC, it is designed for applications where space optimisation, efficient wiring, and versatile functionality are essential. By integrating input and output channels in one module, the EL1852 reduces component count while simplifying cabinet layouts and wiring schemes.

The input channels conform to the EN 61131-2 standard (types 1 and 3), ensuring compatibility with a broad range of industrial sensors and switches. Each input channel operates with a typical current of 3 mA and is equipped with an integrated 3.0 ms input filter, which effectively suppresses noise and guarantees reliable signal acquisition even in environments with significant electrical interference. This makes the terminal ideal for capturing binary signals from devices such as push buttons, limit switches, and proximity sensors.

On the output side, the EL1852 delivers reliable performance with a nominal voltage of 24 V DC. Each output channel is rated to handle up to 0.5 A, with a maximum of 1 A per connection pin, supporting a variety of load types, including indicator lamps, relays, solenoids, and small actuators. The short switching times and stable performance ensure dependable control of connected devices across a range of automation tasks.

A key advantage of the EL1852 is its flat-ribbon cable connection technology, which simplifies wiring and facilitates high-density installations. This approach not only reduces cabling complexity but also accelerates commissioning and maintenance, particularly in applications requiring compact, modular wiring solutions. The flat-ribbon design makes the EL1852 well suited for control cabinets and machine-level installations where space is at a premium.

Like all Beckhoff EtherCAT Terminals, the EL1852 benefits from high-speed, deterministic communication over the EtherCAT protocol. Inputs and outputs are synchronised with the controller in real time, enabling precise coordination of distributed I/O devices. The modular design philosophy of EtherCAT I/O ensures that the EL1852 can be seamlessly combined with other Beckhoff terminals to create customised, scalable automation solutions.

With its combination of input and output functionality, the EL1852 is particularly well suited to applications such as machine automation, packaging equipment, material handling systems, and building technology, where efficient I/O density and straightforward wiring are critical.

In summary, the Beckhoff EL1852 offers a compact, reliable, and versatile solution for digital signal acquisition and actuation. By uniting 8 inputs and 8 outputs in one module, along with robust filtering, flat-ribbon cable connections, and EtherCAT integration, it provides engineers with a cost-effective and space-saving I/O terminal for modern automation environments.
