The Beckhoff EL1004 Digital Input Terminal Module is a compact and efficient solution designed to interface with binary control signals from the process level in industrial automation systems. This module is equipped with four digital inputs, allowing for the acquisition and transmission of signals in an electrically isolated form to the higher-level automation device.
Crafted for reliability and precision, the EL1004 features a nominal input voltage of 24 V DC and includes an input filter with a 3 ms response time to ensure signal integrity. The input current is typically 3 mA, adhering to EN 61131-2, type 1/3 standards. The module's current consumption from the E-bus is approximately 90 mA, highlighting its energy-efficient design.
The EL1004 boasts a robust construction with electrical isolation of 500 V between the E-bus and field voltage, ensuring safe operation and protection against electrical disturbances. The terminal module is designed for mounting on a 35 mm standard mounting rail, conforming to EN 60715, which facilitates easy installation and maintenance.
With a compact footprint of approximately 15 mm x 100 mm x 70 mm, the EL1004 is an ideal choice for space-constrained applications. It operates reliably within an extended temperature range of -25°C to +60°C, making it suitable for a wide range of industrial environments.
The module's status is conveniently indicated by LEDs for each input, providing clear and immediate visual feedback on the operational state. The EL1004 is configured without the need for an address setting, utilising the TwinCAT System Manager for seamless integration into your control system.
The Beckhoff EL1004 Digital Input Terminal Module is a testament to Beckhoff's commitment to quality, offering a dependable and user-friendly interface for digital signal processing in industrial automation applications.
