Description
Decentralized field acquisition and control is handled directly at the machine level by the Beckhoff IP2310-B810 Fieldbus Box. This robust IP67-rated module integrates four digital inputs and four digital outputs into a single compact device, operating via a serial peer-to-peer connection. Designed to withstand harsh industrial environments without requiring an additional protective enclosure, it communicates using an open, documented protocol with support for variable baud rates up to 38.4 kbaud. System parameters and I/O status can be configured and diagnosed seamlessly using the KS2000 software package.
Key Features
-
Direct Field Integration: Fully sealed PA6 polyamide housing providing IP65, IP66, and IP67 protection ratings.
-
Mixed I/O Configuration: Equipped with 4 digital inputs (0.2 ms filter time) and 4 digital outputs (0.5 A per channel).
-
Serial Peer-to-Peer Bus Link: Reliable data transfer via shielded copper cabling up to a distance of 15 meters.
-
Short-Circuit Protection: Sensor supplies and individual output channels feature independent short-circuit protection.
-
Standardized Connections: Employs industry-standard M8 and M12 connections for fieldbus and auxiliary power lines, alongside 8 mm snap-type I/O ports.
Applications
- Decentralized material handling and conveyor automation.
- On-machine sensor and actuator concentration in automotive assembly lines.
- Packaging machinery operating in wet, wash-down, or high-vibration zones.
- Distributed pneumatic valve control terminals.

Empirical Engineering Insights
Alternative Models & Compatibility: The IP2310-B810 relies on a serial point-to-point physical connection. If transitioning system networks to EtherCAT or PROFIBUS, this module is not directly cross-compatible without a coupler box. When replacing legacy IP2310 units, verify the default serial transmission rate (baud rate) match; inconsistencies can cause communication timeouts or frame drops across the 15-meter loop.
Application Pitfalls & Engineering Notes: Although individual outputs are short-circuit proof to 1.5 A typically, the total box sensor supply has a cumulative limit of 0.5 A. Engineers must calculate total current draw of all four connected sensors. Running inductive loads without external flyback diodes is supported by the internal clamping circuit, but excessive cycling of high-inductance coils can generate localized thermal stress in enclosed areas with ambient temperatures approaching 55 degC.
Commissioning & Wiring Tips: To ensure reliable communication at 38.4 kbaud over long lines, use only double-shielded copper cable with a minimum cross-section of 2 x 0.25 mm². Ground the shield on the master controller side. Avoid routing the M8 sensor cables parallel to high-voltage variable frequency drive (VFD) output cables to prevent cross-talk on the 0.2 ms digital input lines.
Installation Guidelines
CRITICAL WARNING: SAFETY FIRST
Always completely isolate and de-energize both the auxiliary power (Us) and load voltage (Up) supply lines before mounting, cleaning, or changing any M8/M12 connections. Failure to follow this protocol can result in transient arcs, sensor failure, or unexpected field actuator state changes.
1
Mount the module on a flat machine frame surface using the two integrated 3.5 mm diameter fixing holes designed for standard M3 screws. Do not exceed 0.8 Nm tightening torque to avoid cracking the polyamide shell.
2
Ensure the IP67 sealing integrity by inserting and fully tightening all M8 and M12 mating connectors. Hand-tighten until the tactile seal resistance is felt, then turn an additional 1/4 turn.
3
Install protective plastic caps on any unused 8 mm snap-type or M8 downstream sockets to maintain environmental protection levels (IP65/66/67).
