Description

The BECKHOFF ERI1809-0021 is an IP67-rated IO-Link box designed to acquire 16 digital input signals in decentralized field environments. Constructed with a highly durable zinc die-cast housing, this module is optimized for direct installation on machines and equipment, eliminating the need for protective control cabinets.

Operating under the IO-Link Specification V1.1 (Class A), the module provides high-speed COM3 transmission rates up to 230.4 kbaud. Standard A-coded M12 connections handle communication and power, while 16 M8 screw-type connection points accommodate sensor inputs. Integrated short-circuit protection and configurable input filters ensure reliable signal collection under demanding industrial conditions.

Features

  • 16 digital input channels via compact M8 screw-type connection points.
  • Supports IO-Link Specification V1.1 (Class A) interface.
  • Fast COM3 data transfer rate (230.4 kbaud) for real-time monitoring.
  • Heavy-duty zinc die-cast housing for rugged mechanical protection.
  • High-level ingress protection with IP65, IP66, and IP67 ratings.
  • Adjustable input filter times (0 to 20 ms) to optimize signal stability.
  • Short-circuit proof sensor supply from L+ up to 0.5 A total.

Applications

  • Decentralized input monitoring on machine frames and conveyor lines.
  • Control-cabinet-free sensor integration in wet or dusty processing plants.
  • Automated assembly and material handling systems using IO-Link architectures.
  • Connection of standard proximity switches and mechanical limit switches.

Installation Guidelines

  1. Verify that the local power supply is de-energized and corresponds to the nominal input voltage range of 24 V DC prior to physical installation.
  2. Mount the zinc die-cast housing securely to the machinery frame using either the two 3.5 mm diameter fixing holes for M3 screws, or the two 4.5 mm diameter fixing holes for M4 screws.
  3. Connect the digital sensor cables to the 16 M8 screw-type connection points. Thread and tighten all plugs appropriately to maintain the IP65/66/67 rating.
  4. Ensure any unused M8 or M12 connections are sealed with appropriate protective caps to prevent dust or moisture ingress.
  5. Connect the IO-Link communication cable to the A-coded M12 interface plug on the module.
  6. Re-energize the system, configure parameters via your IO-Link master, and verify input operation through the diagnostic system.
