Description
Decentralized digital signal processing in harsh industrial environments is facilitated by the Beckhoff EPI2338-0001 IO-Link box. This robust, field-mountable module features eight digital channels that can be individually configured as either inputs or outputs, allowing flexible adaptation to diverse sensor and actuator requirements directly at the machine level. Operating via the standardized IO-Link communication protocol, the device transmits control signals and diagnostic data to the higher-level controller with high efficiency.
The EPI2338-0001 is designed for direct installation on machinery, eliminating the need for protective control cabinets. Its compact form factor and high ingress protection rating make it suitable for space-constrained and demanding applications. The integrated Class B IO-Link interface ensures reliable data transfer rates up to 230.4 kbaud while providing separate power supplies for the module electronics and connected actuators.
Features
- Eight digital channels, individually configurable as inputs or outputs.
- IO-Link V1.1 Class B specification for advanced diagnostics and parameterization.
- High-speed data transfer at 230.4 kbaud (COM3).
- M8 screw-type connectors for secure digital input/output connections.
- Adjustable input filter times ranging from 0 to 20 ms.
- Short-circuit proof sensor and actuator supplies with individual channel protection.
- Electrical isolation between L+ (logic supply) and P24 (actuator supply).
- Robust IP65/66/67 rated housing for cabinet-free field installation.
Applications
- Automated assembly lines and robotics.
- Packaging machinery and material handling systems.
- Machine tool manufacturing and metalworking equipment.
- Decentralized I/O routing in automotive production facilities.

Installation Guidelines
-
Mounting: Can be mounted in any position using the integrated mounting holes. Ensure the mounting surface is flat to prevent mechanical stress on the housing.
-
Grounding: Establish a low-impedance connection to the machine ground using the designated grounding point on the module.
-
Cabling: Use shielded cables for IO-Link communication in high-noise environments. Do not exceed the maximum specified IO-Link cable length of 20 meters.
-
Tightening Torque: Tighten M8 and M12 connectors to the manufacturer-specified torque to maintain the IP65/66/67 ingress protection rating.
