Product Description:
The IP2401-B310 is an I/O compact box unit manufactured by Beckhoff in the IP Compact Box Units series. Installed directly on machinery, it delivers decentralized digital signal handling for controlled devices and sensors within PROFIBUS networks, eliminating the need for separate control cabinets and shortening cable runs in industrial automation cells. Its layout places signal connections close to the machine, which helps keep wiring paths short and supports distributed automation across the installation.
This model provides 8 digital inputs that accept EN 61131-2 Type 2 signals through M8 screw-in connectors, and it offers 8 digital outputs on matching four-pin sockets for field actuators. Communication with the controller occurs over PROFIBUS, so cyclic data exchange fits easily into existing PLC infrastructure. Output channels are supplied from the plant bus at a rated voltage of 24 VDC, and each channel can deliver up to 0.5 A per channel, allowing direct operation of solenoid valves or indicator lamps. Power and downstream signal lines are routed through dedicated M8 four-pin connectors, which simplify daisy-chain installation while maintaining a sealed connection style on the machine.
The input circuitry draws only 6 mA per channel, which reduces sensor loading during operation. A 3.0 ms input filter suppresses contact bounce before values enter the 8-bit process image, helping the controller receive stable switching states. Protection is reinforced by a 1.5 A short-circuit rating that shuts down an overloaded output, and the drivers consume just 20 mA per channel under nominal load to reduce bus current demand. A single four-pin M8 socket serves as the downstream port for extension modules, and the internal sensor supply is matched to the channel limit so external devices receive stable power.
