Description

The BECKHOFF IP2321-B200 is a high-performance, decentralized Fieldbus Box designed to connect digital sensors and actuators directly to a Lightbus industrial network. By combining four digital inputs and four high-current digital outputs into a single module, this device provides space-efficient, distributed intelligence for modern control architectures.

Engineered for direct machine mounting, the BECKHOFF IP2321-B200 eliminates the requirement for protective control cabinets. The integrated B200 Lightbus interface provides rapid optical-fiber communication, ensuring high noise immunity and fast cycle times in demanding industrial environments.

Features

  • Standard Lightbus (B200) interface utilizing optical fiber connectors for reliable, noise-immune communication.
  • Four digital inputs with a 3 ms input filter to suppress signal bounce and electrical noise.
  • Four high-current digital outputs capable of switching up to 2 A per channel, suitable for solenoid valves and actuators.
  • Industry-standard M8 screw connectors for secure signal routing and rapid cabling.
  • Sealed, compact housing designed for direct installation on machinery and equipment.

Applications

  • Decentralized input and output data acquisition on packaging and assembly machinery.
  • Direct control of high-current pneumatic valves and solenoids without auxiliary relays.
  • Optical fiber communication setups requiring immunity to electromagnetic interference (EMI).

Installation Guidelines

  1. Ensure that the entire system power supply is de-energized and locked out before starting the installation process.
  2. Mount the BECKHOFF IP2321-B200 securely to the machine chassis using the integrated mounting holes.
  3. Inspect and clean the fiber optic connectors of the Lightbus cables prior to insertion to prevent signal attenuation.
  4. Connect the Lightbus fiber optic cables, verifying the correct physical ring topology (IN to OUT sequence).
  5. Thread and secure the M8 sensor and actuator cables, ensuring the connectors are hand-tightened to maintain environmental integrity.
  6. Apply the 24 V DC control and load voltages, then verify status indication indicators on the module during initial boot.

Replacement Recommendations

When replacing an existing BECKHOFF IP2321-B200 module, label all fiber optic and M8 connections to ensure exact relocation. Check fiber optic end-faces for dust or damage, cleaning them with specialized optical tools if necessary before insertion into the replacement unit.
