Boîtier d'extension E/S numérique Beckhoff IE2320

Product Overview

The Beckhoff IE2320 (IE2320) is a compact, robust field-ready Extension Box designed to provide versatile digital I/O capabilities directly at the machine level. Featuring 4 digital inputs and 4 digital outputs, this module is engineered for harsh environments where a high Ingress Protection (IP) rating is essential. By utilizing an IP65/66/67-rated polyamide housing, the IE2320 eliminates the need for expensive control cabinets, allowing for distributed control architectures that reduce cabling complexity and accelerate machine assembly.

Technical Configuration

The IE2320 is built for demanding automation tasks, supporting ohmic, inductive, and lamp loads. Each of the four outputs is individually short-circuit proof, capable of delivering up to 2 A per channel, with a total aggregate current of 4 A. The input stage conforms to EN 61131-2 (Type 2), ensuring compatibility with a wide range of industrial sensors. Electrical isolation is maintained between the control voltage and the fieldbus via the proprietary IP-Link, protecting the central controller from field-side surges. The module features M8 connectors for both I/O signals and power feed, facilitating a "plug-and-play" installation experience.

Technical Specifications

FAQs

Why is there no electrical isolation between channels?

The IE2320 is designed for high-density, distributed I/O applications where space and cost are prioritized. In most standard sensor/actuator applications, common referencing is sufficient. If your application requires channel-to-channel isolation, consider an alternative terminal block or a galvanic isolation module.

Can this module be used in wash-down applications?

Yes, with an IP65/66/67 rating, the module is fully protected against dust-tight environments and powerful water jets, making it an excellent choice for food processing, packaging, or outdoor industrial machinery.

How is the sensor supply managed?

The sensor supply is derived directly from the 24 V DC control voltage. The total sensor supply is limited to 0.5 A and is short-circuit protected. Ensure your cumulative sensor current draw does not exceed this 0.5 A threshold.

What is the "Snap type" connection technology?

The snap-type M8 connection provides a quick-disconnect interface that speeds up installation and replacement. It is designed to maintain a secure, vibration-resistant electrical contact without the need for traditional screw-on couplings.

Installation Guidelines and Best Practices

• Mounting: Use the two 3.5 mm diameter fixing holes with M3 screws to mount the module onto a machine frame or mounting plate. Ensure the surface is flat to avoid twisting the polyamide housing, which could compromise the IP sealing.
• Cabling: Use shielded cables for the IP-Link connection to ensure signal integrity across your distributed I/O nodes, especially if the module is mounted near high-current motors or frequency converters (VFDs) that generate significant EMI.
• Power Distribution: The IE2320 features a power feed (M8 male) and a downstream connection (M8 female). This allows for efficient daisy-chaining of power to multiple Extension Boxes. Be mindful of the total current draw when cascading modules to prevent voltage drops along the supply line.
• Environment: While the IP67 rating is robust, ensure the cable connections are fully seated. If a port is not in use, install an M8 protective cap to maintain the integrity of the enclosure against environmental ingress.
