Description

Designed for direct installation in demanding industrial environments without a control cabinet, the IP2301-B400 provides a robust interface between Interbus networks and decentralized field sensors or actuators. This fieldbus box features a balanced combination of four digital inputs and four digital outputs in a compact, IP67-rated housing. By routing physical signals directly at the machine level, the module significantly minimizes wiring overhead, simplifies diagnostics, and optimizes signal propagation times.

The integrated digital inputs feature a 3 ms filter time to prevent contact bounce issues, while the short-circuit-proof digital outputs deliver up to 0.5 A per channel. Standardized M8 connectors ensure secure, vibration-resistant sensor and actuator cabling, making this unit highly suitable for dynamic mechanical setups.

Features

Direct Interbus fieldbus connection for high-speed decentralized communication.
Four digital inputs (24 V DC) with an integrated 3 ms input filter.
Four short-circuit proof digital outputs rated at 0.5 A per channel.
Compact, space-saving design with robust M8 connection technology.
IP67 protection class allowing direct mounting on machines without protective enclosures.

Applications

Decentralized machine control and plant automation architectures.
Automotive manufacturing assembly lines utilizing Interbus fieldbus networks.
Material handling, packaging machinery, and conveyor line routing.
Industrial robotics and end-of-arm tooling control setups.

Installation Guidelines

Mount the module directly to a flat machine frame or structure using the integrated mounting holes.
Ensure reliable grounding of the module case to the machinery frame to maximize electromagnetic compatibility (EMC).
Tighten all M8 mating connectors to the recommended torque specifications to maintain the IP67 environmental seal.
Route fieldbus and low-voltage control lines separate from high-noise power cables or AC motor drives to prevent signal interference.
