Description
The BECKHOFF IP2301-B800 is a compact Fieldbus Box module designed for direct machine mounting in distributed automation systems. It integrates four digital inputs and four digital outputs within a sealed, IP67-rated enclosure, enabling reliable signal processing without the need for an external control cabinet. The module utilizes an RS485 serial communication interface running an open, documented protocol, allowing direct integration into host control systems or serial fieldbus networks.
Operating from a 24 V DC supply, the module processes binary sensor signals using a 3.0 ms input filter conforming to EN 61131-2 Type 2 specifications. The four digital outputs support load currents of up to 0.5 A per channel for resistive, inductive, or lamp loads, with built-in short-circuit proofing and reverse polarity protection. Signal connections are established using industrial M8 screw-type connectors, and LED status indicators on the front panel provide clear operational diagnostics for each channel and bus communication state.
Features
- Combines 4 digital inputs and 4 digital outputs in a single compact housing
- RS485 serial fieldbus communication supporting transfer rates up to 38.4 kbaud
- High ingress protection rated at IP65, IP66, and IP67 for harsh environments
- Individually short-circuit proof 0.5 A digital outputs with inverse polarity protection
- Direct M8 screw-type connection for industrial sensors and actuators
- Integrated feed and downstream M8 power connectors for looped control voltage distribution
- Configurable operating parameters using BECKHOFF KS2000 software
- Optical status LEDs indicating bus activity and I/O switching states
