Description

The BECKHOFF ERI2339-0021 is a zinc die-cast IO-Link box designed for distributed digital signal processing in demanding industrial environments. Operating as an IO-Link device, this module features 16 digital channels that can be configured individually as either inputs or outputs. It interfaces with any standard IO-Link master via a secure M12 A-coded plug connection, facilitating efficient field-level communication and parameterization.

Engineered to the IO-Link Class B specification, the BECKHOFF ERI2339-0021 incorporates isolated supply paths to support both logic and auxiliary load power. Connection to field sensors and actuators is established via 16 M8 screw-type sockets. Its rugged metal enclosure provides superior mechanical stability and environmental protection, making the module suitable for cabinet-free installation directly on machinery.

Features

  • 16 digital channels, each fully configurable as an input or an output
  • IO-Link Class B communication conforming to V1.1 specifications
  • High-speed transmission rate of 230.4 kbaud (COM3)
  • Robust zinc die-cast housing with IP65, IP66, and IP67 ingress protection
  • Short-circuit proof sensor power distribution and individual output load protection
  • Adjustable input filter times for optimal signal processing
  • Compact design allowing direct machine-mount installation without a protective control enclosure

Applications

  • Decentralized input/output signal processing on modern assembly systems
  • Machine tool manufacturing and packaging lines with heavy mechanical vibrations
  • Robot end-effector tool integration where space and weight are restricted
  • Material handling conveyor tracks requiring localized sensor and actuator distribution

Connections / Interfaces

The module interfaces directly to the field level and the control level through integrated IP67 connectors. All interfaces must be capped or sealed to maintain environmental protection ratings.

Interface Type Function
M12 Plug (A-coded) Main IO-Link interface and power supply connection (Class B), supplying communication, logic, and output load power.
16 x M8 Sockets Configurable digital input/output channels. Screw-type connectors provide physical wiring to standard industrial sensors and actuators.

Installation Guidelines

  1. Inspection: Examine the module housing, sealing rings, and terminal pins for physical damage before mounting.
  2. Mounting: Mount the device directly onto a level surface of the machine. Secure the housing using either two M3 bolts through the 3.5 mm holes or two M4 bolts through the 4.5 mm holes.
  3. Power Isolation: De-energize all logic and field auxiliary supply voltages (L+ and P24) before installing or disconnecting any wiring.
  4. Cable Connection: Connect the M12 IO-Link Class B master line. Ensure all M8 field cabling for sensors and actuators is hand-tightened to seal the interfaces.
  5. Grounding: Ensure the metallic zinc die-cast housing has low-resistance contact with the grounded machine frame to maintain EMC immunity.
  6. Commissioning: Power up the IO-Link system, load the correct IODD configuration file, and verify that communication rates are negotiated to 230.4 kbaud (COM3).
