EL1872-0010 | BECKHOFF | EtherCAT Terminal 16-Channel Digital Input Module

Description

The EL1872-0010 is a high-density 16-channel digital input terminal from Beckhoff, optimized for industrial automation systems requiring compact signal acquisition. This terminal utilizes ground switching technology and is designed specifically for flat-ribbon cable connectivity, streamlining the wiring process for high-channel-count applications. With a rapid 10 µs input filter, it provides fast and precise monitoring of 24 V DC signals, making it suitable for high-speed sensor interfacing within an EtherCAT network.

Features

• 16 digital input channels in a compact housing
• Ground switching (0 V) logic interface
• Fast 10 µs input filter for high-speed response
• Efficient flat-ribbon cable connectivity (AWG 28)
• Integrated signal LEDs for per-channel status monitoring
• Electrical isolation of 500 V between E-bus and field potential

Technical Specifications

Installation Guidelines

• Connection: The terminal is designed for use with standard flat-ribbon cables (1.27 mm spacing, AWG 28). Ensure correct orientation of the ribbon cable connector to prevent signal misalignment.
• Mounting: Secure to a standard 35 mm DIN rail (EN 60715) using the integrated lock. The terminal supports side-by-side mounting via a double slot and key connection.
• Power Supply: The module consumes approximately 45 mA from the 24 V supply for internal operations (excluding field load). Ensure your power supply capacity accounts for the cumulative load of all 16 channels.
• Environmental: The unit is IP20 rated. Maintain operation within the specified 0 to +55 degC range to ensure long-term reliability.
