Description

The BECKHOFF ER4374-0002 is an EtherCAT Box designed for direct field mounting outside of control cabinets. This combi module features two analog inputs and two analog outputs that are individually parameterizable for either voltage or current signals. This flexibility allows for the integration of diverse analog sensors and actuators directly into the EtherCAT network in harsh industrial environments.

Constructed with a durable zinc die-cast housing, the ER4374-0002 provides excellent structural stability and high electromagnetic compatibility (EMC). It offers IP67 protection, making it highly resistant to dust, moisture, and liquids. The fieldbus connections, power supply, and signal interfaces are established via industrial-grade circular connectors, ensuring secure and stable wiring.

The integrated 16-bit resolution provides high-precision measurement and signal output. Because the inputs and outputs can be configured independently, this module optimizes space and reduces hardware variants in machine installations, serving as a versatile interface for automation and control tasks.

Features

  • Combination module with 2 analog inputs and 2 analog outputs in a single housing
  • Individually parameterizable channels for voltage (-10 V to +10 V) or current (0/4 mA to 20 mA) signals
  • Zinc die-cast housing designed for direct machine installation without protective enclosures
  • High-precision signal processing with 16-bit resolution
  • Standardized industrial connections with M12 sockets for signal interfaces
  • Dual M8 sockets for high-performance EtherCAT communication
  • High protection rating of IP67 for demanding industrial environments

Applications

  • Direct integration of analog sensors and actuators in decentralized machine architectures
  • Process measurement and closed-loop control systems in harsh environments
  • Applications requiring mixed analog input and output signals at localized stations
  • Machine tool manufacturing, assembly automation, and material handling systems

Installation Guidelines

  1. Verify that the model number ER4374-0002 matches your system specifications prior to installation.
  2. Ensure all power sources are fully de-energized before mounting or wiring the module to prevent electrical shock or equipment damage.
  3. Mount the module securely to a flat machine surface or mounting bracket using the designated mounting holes.
  4. Connect the EtherCAT fieldbus cables using shielded M8 connectors, ensuring correct port allocation.
  5. Wire the analog sensors and actuators to the M12 signal sockets according to the parameter requirements (voltage or current).
  6. Establish the 24 V DC power connections using the M8 power connectors, ensuring proper potential and polarity alignment.
  7. Ensure all unused connectors are sealed with appropriate protective caps to maintain the IP67 protection rating.
  8. Perform a commissioning and diagnostic check via the master configuration software (such as TwinCAT) to verify parameter settings and signal continuity.
