BECKHOFF EPP4374-0002 EtherCAT P Box

Description

The BECKHOFF EPP4374-0002 is a high-performance, decentralized EtherCAT P Box designed for directly acquiring and processing analog signals in harsh industrial environments. Serving as a combined input and output module, this unit features two analog inputs and two analog outputs, each of which can be individually parameterized for current or voltage signals. This adaptability makes it highly versatile for connecting diverse sensors and actuators directly in the field without requiring local junction boxes.

By utilizing EtherCAT P technology, the BECKHOFF EPP4374-0002 combines ultra-fast EtherCAT communication with two independent 24 V DC power supplies (Us for system and sensor electronics, and Up for peripheral actuator power) into a single M8 connector system. This integration significantly simplifies field wiring, minimizes system footprints, and reduces overall cable management costs.

Enclosed in a robust, compact housing with an IP67 protection rating, the module resists moisture, dust, and mechanical stress. It is ideal for direct machine mounting, eliminating the need for protective control cabinets and ensuring clean, high-resolution signal processing directly at the point of application.

Features

• Combined configuration featuring 2 analog inputs and 2 analog outputs.
• Individually parameterizable channels for voltage (-10 to +10 V, 0 to 10 V) or current (0 to 20 mA, 4 to 20 mA) signals.
• High-resolution 16-bit analog-to-digital and digital-to-analog conversion for precise signal monitoring and control.
• EtherCAT P interface combining communication and supply power in a single, space-saving connection.
• Standard M12 x 1, 5-pin, A-coded sockets for robust field connections to actuators and sensors.
• Fully encapsulated IP65, IP66, and IP67-rated enclosure suitable for cabinet-free installation.

Applications

• Direct machine mounting in space-constrained industrial installations.
• Distributed analog sensor and actuator integration in automated production lines.
• Precise current and voltage measurement and output control in feedback systems.
• Field-level signal processing in modular machinery using EtherCAT P topologies.

Installation Guidelines

1. Verify System State: De-energize all power supplies before starting mechanical installation or wiring procedures.
2. Physical Mounting: Securely mount the module directly to the machine body or mounting frame using the designated mounting holes. Ensure the mounting surface is flat to avoid mechanical stress on the housing.
3. EtherCAT P Wiring: Connect the incoming EtherCAT P cable to the input M8 socket and, if daisy-chaining, connect the next module via the output M8 socket. Use only shielded, P-coded M8 connectors to maintain protection and signal integrity.
4. Signal I/O Connection: Connect the analog sensors and actuators to the M12 sockets. Use shielded cables for all analog lines to minimize electromagnetic noise and interference.
5. Grounding: Ensure the module is grounded adequately according to local regulations, utilizing the grounding connection points if provided or via the mounting screws on a conductive, grounded surface.
6. Commissioning: Power up the system and verify the status LED indications. Configure the signal parameters (voltage or current) for each channel within your TwinCAT development environment.
