Description

The Beckhoff EP2349-0021 is a highly adaptable decentralized EtherCAT Box designed for direct field integration without an environmental enclosure. Featuring 16 digital channels, this module allows each channel to be independently configured as either an input or an output, offering flexible channel management for complex control systems. Encased in a rugged polyamide housing, it ensures high reliability under demanding industrial conditions. Field communication is established via robust, shielded M8 screw-type connections, while standard sensors and actuators connect through A-coded M8 3-pin interfaces.

Features

16-channel digital flexibility allowing individual configuration as either inputs or outputs.
Robust PA6 polyamide housing providing IP65, IP66, and IP67 ingress protection.
Shielded M8 screw-type connectors for high-integrity EtherCAT bus communication.
Individually short-circuit proof digital outputs with a maximum continuous sum current of 4 A.
Integrated sensor supply sourced from the load supply voltage, protected against short circuits.
Dual-hole physical installation options accommodating M3 and M4 fasteners.

Applications

Automated assembly and conveyor lines.
Decentralized packaging and material handling machinery.
Machine tool monitoring and robotic end-of-arm tooling.
Process manufacturing systems operating in wet or dusty field environments.

Installation Guidelines

Mounting: Attach directly to flat surfaces using the integrated mounting guides. Use two 3.5 mm diameter holes for M3 screws or two 4.5 mm diameter holes for M4 screws.
Shielding and Grounding: Ensure proper grounding connection of the box profile. EtherCAT communication cables must be fully shielded and properly torqued to guarantee IP ratings and noise immunity.
Power Supply Configuration: Verify that the total load current from all active output channels does not exceed the sum limit of 4 A to protect upstream power distribution.

UL
Conforms to EN 61131-2, type 1/3 (digital inputs)
EMC Immunity/Emission conforms to EN 61000-6-2 and EN 61000-6-4
Vibration/Shock Resistance conforms to EN 60068-2-6 and EN 60068-2-27

Key Features:

Can the digital channels on the EP2349-0021 be configured individually?

Yes, the 16 digital channels can be individually and freely configured to operate either as inputs or as outputs based on system requirements.

What connector style is used for the sensor and actuator connections?

The input and output connections utilize standard M8 x 1, 3-pin, A-coded sockets.

Does the EP2349-0021 require an electrical enclosure for protection?

No, with its IP65, IP66, and IP67 protection ratings, this module is specifically engineered for direct field-level installation without an enclosure.

What is the maximum total output current for the module?

While each channel can handle up to 0.5 A individually, the total sum of output current across all channels must not exceed 4 A.
