Description

Designed for decentralized industrial automation environments, the Beckhoff IP2301-B310 is a rugged, field-mountable I/O module operating on the PROFIBUS DP network protocol. This unit features a combined configuration of four digital inputs and four digital outputs, allowing for local integration of sensors and actuators directly on processing machinery. By eliminating the necessity for protective control cabinets, this Fieldbus Box optimizes installation footprints and significantly reduces field-wiring complexity.

The module communicates at high speeds with automatic baud rate detection up to 12 Mbaud, ensuring deterministic performance within time-critical automation systems. It features M8 interfaces for robust signal distribution and an M12 B-coded connection for secure PROFIBUS network coupling.

Features

Four 24 V DC digital inputs with integrated 3.0 ms input filtering.
Four 24 V DC digital outputs rated at 0.5 A per channel, suitable for resistive, inductive, and lamp loads.
Automatic baud rate detection up to 12 Mbaud for seamless integration into PROFIBUS DP networks.
Individually short-circuit proof outputs with transient protection.
Rugged polyamide housing (PA6) offering IP65, IP66, and IP67 protection classes.
Direct machine mounting with integrated dual-point fixing slots.

Applications

Automotive assembly and conveyor systems.
Packaging, sorting, and material handling lines.
Decentralized machine tool control.
Food and beverage processing plants requiring washdown-rated components.

Installation Guidelines

Mount the module vertically or horizontally on flat machinery surfaces using two 3.5 mm mounting holes designed for M3 fasteners.
To maintain the IP65/66/67 ingress protection rating, ensure all unused M8 and M12 ports are sealed with approved protective caps.
Route communication cables separately from high-voltage AC lines to prevent electromagnetic interference.
Verify that the cumulative current draw of the sensor supply and outputs does not exceed the module's specified power connection limits.

Key Features:

What is the ingress protection rating of the Beckhoff IP2301-B310?

The module is rated at IP65, IP66, and IP67 under standard EN 60529, meaning it is dust-tight and highly resistant to water jets and immersion, allowing cabinet-free machine mounting.

Does the IP2301-B310 support automatic baud rate detection?

Yes, it automatically detects transmission speeds on the PROFIBUS DP network up to 12 Mbaud.

What is the maximum current capacity per output channel?

Each of the 4 digital outputs can supply up to 0.5 A, and every channel is individually protected against short circuits.

What connection types are used for the sensors and actuators?

The digital inputs and outputs on the IP2301-B310 utilize rugged, screw-type M8 connections.
