Product Profile

The ProSoft PLX51-HART-4I is a 4-channel HART input module that enables EtherNet/IP control systems to read process variables, diagnostic data, and device status from HART-enabled field instruments. It provides a direct interface between HART field devices and Rockwell Automation PLCs, supporting both 4-20 mA analog signals and digital HART communication on each channel.

Designed for process automation applications, the PLX51-HART-4I simplifies integration of smart transmitters, valve positioners, and flow meters. Its built-in web diagnostics allow for real-time monitoring of HART device health and communication quality.

Technical Data

System Role

The PLX51-HART-4I functions as a data acquisition module, converting HART digital information and 4-20 mA analog signals into EtherNet/IP data that can be consumed by Rockwell Automation controllers. It supports concurrent analog and digital communication on all four channels, providing comprehensive process visibility without additional wiring or multiplexers.

Compatibility

• Compatible with Rockwell Automation ControlLogix and CompactLogix platforms.
• Works with HART 5, 6, and 7 field devices.
• Supports all standard 4-20 mA HART transmitters and valve positioners.
• Configuration via ProSoft Configuration Builder and web interface.

Typical Applications

• Process variable monitoring from smart pressure and temperature transmitters.
• Valve positioner diagnostics and control.
• Flow meter data acquisition in oil and gas applications.
• Tank level monitoring and inventory management.
