BECKHOFF IP1502-B520 Fieldbus Box

Description

The BECKHOFF IP1502-B520 is a high-performance, decentralized 2-channel digital input counter module designed to interface directly with DeviceNet industrial networks. This Fieldbus Box is built to capture rapid pulse counts and process high-frequency input signals independently of the fieldbus cycle time, ensuring precision in demanding industrial synchronization and measurement applications.

Equipped with 2 independent 32-bit counter channels, the module features a comprehensive set of auxiliary signal lines, including 2 gate inputs and 2 up/down switches. This configuration allows for real-time control over counting direction, enabling versatile configuration options directly on the machine. To facilitate direct sensor connection, the module provides a short-circuit-proof 24 V DC sensor supply alongside two short-circuit-proof digital outputs rated at 0.5 A each.

Housed in a rugged, low-profile polyamide enclosure, the BECKHOFF IP1502-B520 boasts an IP65/66/67 protection rating, allowing direct machine mounting without the need for an additional protective electrical cabinet. Signal and power lines are easily managed via industry-standard M12 and M8 connections, making it an excellent choice for decentralized physical architectures.

Features

• Direct DeviceNet integration with automatic baud rate detection up to 500 kbaud.
• Two independent 32-bit counter channels with a maximum counting frequency of 100 kHz.
• Configurable counting behavior with 2 gate inputs and 2 up/down direction switches.
• Integrated sensor supply derived from control voltage, providing up to 0.5 A short-circuit-protected output.
• Two short-circuit-proof 24 V DC auxiliary digital outputs rated at 0.5 A.
• M12 screw-type signal connections and M8 control voltage distribution connectors.
• Rugged polyamide (PA6) housing requiring no protective control cabinet.

Applications

• Decentralized high-speed piece and pulse counting in conveyor and sorting lines.
• Position, distance, and velocity measurement utilizing incremental rotary encoders.
• Decentralized flow meters and liquid dosing measurement.
• On-machine installation in wet, dusty, or high-vibration manufacturing environments.

Installation Guidelines

1. Ensure the system power supply is fully de-energized and locked out before initiating mounting, connection, or service tasks.
2. Verify the identity of the device to ensure it matches model number IP1502-B520.
3. Mount the module directly to a clean, flat surface using two M3 bolts through the integrated 3.5 mm mounting holes. No enclosure is required.
4. Connect the DeviceNet communication line using the designated 5-pin M12 bus cable connector.
5. Connect the 24 V DC feed voltage to the 4-pin M8 male connector. If daisy-chaining multiple Fieldbus Box modules, link the 4-pin M8 female downstream connector to the next device.
6. Wire all sensor and output field devices to the corresponding M12 channels. To preserve the IP65/66/67 rating, seal any unused M12 and M8 ports with tightly screwed protective caps.
7. Apply power to the control supply loop and configure the DeviceNet master scanner or use the KS2000 configuration tool to map the process image.
