Product Description

The Beckhoff EL1144-0000 is a 12 V digital input terminal that effectively acquires binary control signals from various sensors. It features a "0" signal voltage threshold of less than 2.4 V and a "1" signal voltage threshold of greater than 8.5 V. The low "0" signal voltage allows for effective noise immunity, preventing false triggering from voltage fluctuations in industrial environments. The high "1" signal voltage threshold ensures that only strong signals from compatible sensors are recognized as active, minimizing the risk of unintended activations. The terminal is equipped with four inputs, enabling the simultaneous monitoring of multiple binary control signals from various sensors. Each input operates at a nominal voltage of 12 V DC, making it suitable for interfacing with a wide range of industrial sensors.

This terminal utilizes 2/3-wire connection technology, which allows seamless connectivity with a wide range of sensors. It can effectively support standard 2-wire connections for simple binary signals and 3-wire connections for more complex sensor setups. The terminal incorporates a fast input filter with a low delay of just 10 µs, ensuring quick response times for signal acquisition. This makes it suitable for time-sensitive applications. The terminal provides dedicated +12 V and 0 V sensor supply connections, simplifying the integration process.

The input current for this terminal is rated at 3 mA, ensuring system efficiency. It features a 12 mm x 100 mm x 68 mm lightweight form that is easy to fit into control cabinets. The terminal has a weight of just 55 g, delivering a compact and versatile solution in a wide range of automation setups. Its polycarbonate housing keeps the terminal protected from damage caused by environmental elements ensuring reliable performance and longevity.
