Description

Designed for decentralized automation tasks, the EP4378-1022 accommodates high-density digital and analog signals within a ruggedized, field-mountable housing. This Beckhoff EtherCAT Box serves as a versatile combination module, integrating 8 digital inputs, 8 digital outputs, 4 analog inputs, and 4 analog outputs. By providing comprehensive I/O capabilities directly on the machine, it eliminates the requirement for protective control cabinets and complex terminal boxes.

The analog channels on the module are highly adaptable, supporting both current and voltage modes (-10/0 to +10 V or -20/0/4 to +20 mA) customizable per individual channel at a precise 16-bit resolution. Built-in M12 connector interfaces ensure sealed, vibration-resistant connections under demanding industrial conditions, drastically reducing field wiring complexity and installation time.

Features

Combination module with 8 digital inputs/outputs and 4 analog inputs/outputs.
Parameterizable analog signals (voltage or current) configurable per channel.
High 16-bit resolution for precise analog-to-digital and digital-to-analog signal processing.
Direct field installation with IP65, IP66, and IP67 ingress protection ratings.
Dual M8 shielded, screw-type socket interfaces for high-speed EtherCAT communication.
Integrated actuator supply derived from the auxiliary voltage UP (short-circuit proof).
Electrical isolation of 500 V to isolate external field potentials from the EtherCAT network.

Applications

Decentralized field instrumentation and sensor arrays in assembly plants.
Machine tool control and localized factory automation networks.
Process control systems in wet, dusty, or demanding industrial environments.
Material handling systems requiring high-density localized I/O routing.

Installation Guidelines

Mount securely to an industrial machine frame or mounting plate using the integrated screw holes. Installation is permitted in variable positions.
Ensure all mating M8 and M12 connectors are tightened to the recommended torque specifications to maintain the IP65/66/67 physical seal.
Route signal and EtherCAT cables separately from high-voltage AC power lines to prevent electromagnetic interference.
Ground the device using the designated connection point to safeguard communication integrity in electrically noisy environments.

Compliance and Certifications

Key Features:

What is the physical protection rating of the Beckhoff EP4378-1022?

The EP4378-1022 features an IP65/66/67 protection rating (conforming to EN 60529), making it completely dust-tight and resistant to water jets and temporary immersion, enabling direct installation in harsh field environments without an enclosure.

Can the analog channels be individually configured for different signal types?

Yes, each of the 4 analog inputs and 4 analog outputs is parameterizable individually for either voltage (-10/0 to +10 V) or current (-20/0/4 to +20 mA) depending on your field device requirements.

What is the resolution and conversion speed for the analog channels?

The module operates with a high 16-bit resolution. The signal conversion time is approximately 100 microseconds for inputs and 40 microseconds for outputs.

How is power distributed to downstream EtherCAT Box modules?

The module features a 4-pin M8 male power inlet for the feed, and a 4-pin M8 female socket for downstream connection, allowing you to daisy-chain the power supply (US/UP) to adjacent modules.
