Description

The BECKHOFF IP2312-B730 is a compact Fieldbus Box designed for direct machine mounting in demanding industrial environments. Operating as a decentralized I/O station, this module interfaces digital peripheral signals with serial networks utilizing the Modbus RTU/ASCII protocol. It features a combination of four digital inputs and four digital outputs, providing a highly integrated solution for localized sensor and actuator connection without the need for a protective control cabinet.

Constructed with a polyamide housing, the BECKHOFF IP2312-B730 achieves an IP65/66/67 protection rating, making it highly resistant to wet, dusty, or harsh operating conditions. Its design allows direct installation on machines using two simple mounting holes, reducing wiring complexity, minimizing cabinet space requirements, and simplifying field-level diagnostics.

Features

  • Modbus RTU/ASCII serial communication interface (RS485) supporting data transfer rates from 150 to 38,400 baud.
  • Integrated I/O configuration consisting of 4 digital inputs (24 V DC) and 4 digital outputs (24 V DC, 0.5 A).
  • High-density physical connections utilizing standard M12 screw-type connectors for secure field cabling.
  • Short-circuit proof digital outputs with individual channel protection capable of switching ohmic, inductive, and lamp loads.
  • Integrated address selection switches for quick network configuration and node addressing.
  • IP65/66/67-rated polyamide housing suitable for variable mounting orientations without a protective enclosure.

Applications

  • Decentralized machine-mount sensor and actuator integration in automated assembly lines.
  • Localized digital signal processing in conveyor systems and material handling machinery.
  • Direct-to-field fieldbus expansion in wet or dusty industrial manufacturing environments.
  • Modbus RTU serial network deployment where control cabinet space is limited or restricted.

Installation Guidelines

  1. De-energize the System: Ensure all power supplies (control voltage and auxiliary load supplies) are turned off before mounting, wiring, or configuring the device.
  2. Physical Mounting: Mount the module directly onto a flat surface or machine framework using the two 3.5 mm integrated mounting holes with suitable M3 screws. Ensure the mounting surface is clean and free of excessive vibration.
  3. Configure Addressing: Set the serial network address using the integrated rotary address selection switches or configure the device via the KS2000 software interface prior to securing the protective caps.
  4. Connect Fieldbus: Connect the RS485 Modbus serial line to the B-coded 5-pin M12 fieldbus interface socket.
  5. Wiring I/O and Power: Securely connect sensors and actuators to the M12 I/O channels. Connect the 24 V DC supply feed to the 4-pin M8 male connector. If daisy-chaining power, connect the downstream cable to the 4-pin M8 female socket.
  6. Seal Unused Ports: To maintain the IP65/66/67 environmental protection rating, fit protective caps on all unused M12 and M8 connector sockets.

FAQ

What protocol does the BECKHOFF IP2312-B730 Fieldbus Box use?

The BECKHOFF IP2312-B730 uses the Modbus RTU/ASCII serial protocol over an RS485 physical interface, supporting adjustable baud rates from 150 to 38,400 baud.

What is the physical connection configuration of the BECKHOFF IP2312-B730?

The BECKHOFF IP2312-B730 features four digital inputs and four digital outputs utilizing standard M12 screw-type connections, while serial fieldbus communication is handled by a B-coded 5-pin M12 socket.

Does the BECKHOFF IP2312-B730 require a protective control cabinet?

No, the BECKHOFF IP2312-B730 is designed for direct machine installation. Its rugged polyamide housing provides an IP65/66/67 protection rating, making it resistant to dust, moisture, and spray water without needing an enclosure.

How are the inputs and outputs powered on the BECKHOFF IP2312-B730?

The BECKHOFF IP2312-B730 is supplied with 24 V DC control voltage through a 4-pin M8 male connector. The sensor supply is drawn from this control voltage up to a maximum of 0.5 A in total. Auxiliary load voltage is wired using the downstream M8 female connector for daisy-chain configurations.

Is there electrical isolation between the channels and control logic on the BECKHOFF IP2312-B730?

The BECKHOFF IP2312-B730 features complete electrical isolation between the control voltage/internal electronics and the serial fieldbus. However, there is no electrical isolation between the individual digital I/O channels themselves or between the channels and the internal control voltage supply.
