Product Description

The EL1018, manufactured by Beckhoff, is a crucial component within their EL EtherCAT Terminal Series. Designed for industrial automation, this terminal boasts eight digital inputs, facilitating the acquisition of signals from various sources like sensors, switches, and encoders. These inputs operate at a nominal voltage of 24 V DC, a standard in industrial control systems, with an allowable fluctuation of -15% to +20% to accommodate voltage variations. This flexibility ensures reliable operation even under less-than-ideal conditions. Each input is designed to recognize signals according to EN 61131-2, a widely recognized standard for programmable logic controllers (PLCs). A "0" signal is registered at a voltage between -3V and +5V, while a "1" signal is recognized between 11V and 30V. This wide voltage range for signal recognition increases the terminal's compatibility with various sensors and devices.

The EL1018 incorporates an input filter with a typical response time of 10 µs to ensure signal integrity. This filter helps to suppress electrical noise and transient voltages, preventing false triggering and providing accurate data acquisition. Beyond signal processing, the EL1018 is engineered for robustness and reliability in demanding industrial environments. Its IP20 protection rating signifies protection against solid objects larger than 12mm, such as fingers, but not against liquids. This rating suits typical industrial control cabinets where direct liquid exposure is unlikely. The terminal's operating temperature range spans from -25°C to +60°C, allowing it to function reliably in various industrial settings, from cold storage facilities to hot factory floors. Furthermore, the EL1018 adheres to EN 61000-6-2/EN 61000-6-4 EMC standards, ensuring its electromagnetic compatibility with other devices and minimizing interference.

Internally, the EL1018 consumes a typical 3 mA per input current, contributing to its overall energy efficiency. The power contacts draw a typical current of 2 mA plus the load current, while the E-bus, responsible for communication within the EtherCAT network, consumes a typical current of 90 mA. The terminal can be stored at temperatures between -40°C and +85°C, offering flexibility in storage and transportation. It is also designed to withstand vibrations and shocks per EN 60068-2-6/EN 60068-2-27 standards, further enhancing its suitability for harsh industrial conditions. Wake Industrial offers a one-year warranty on this product, providing buyers with added assurance and peace of mind.
