PROSOFT PLX51-HART-4I

1. Product Overview

The PLX51-HART-4I solves the communication gap between traditional process instruments (such as pressure and flow transmitters) and modern Ethernet-based control systems. It converts HART device data into Ethernet-compatible protocols, allowing PLCs, SCADA systems, and host computers to directly read and control field instruments.

2. Key Specifications

Communication Channels

• 4 independent HART channels

Electrical Characteristics

• Resolution: 12-bit ADC
• Input impedance: 247.5 Ω
• Accuracy: < 0.15% calibrated, < 0.30% uncalibrated
• Measuring range: 0 to 22 mA
• Current limiting: 34 mA

Network Interface

• Physical: RJ45 port, compatible with Cat5 STP/UTP cables
• Protocols: EtherNet/IP, Modbus TCP/IP, DNP3 (TCP/UDP), PCCC (AB-ETH)
• Connection capacity: Up to 20 ARP/TCP connections, 10 CIP connections

3. Main Features

• Multi-drop Communication: Supports up to 4 HART devices in multi-drop mode, reducing wiring costs.
• Direct Access & Customization: Allows custom HART messaging for direct device access and advanced diagnostics.
• Easy Integration: Works with the ProSoft PLX50 Configuration Utility and supports hot-swapping for simplified maintenance.
• Broad Compatibility: Interoperable with various HART-enabled instruments, including 4-20 mA and 0-20 mA devices.

4. Structure & Components

Front Panel

• 6 LED indicators (Ok, Eth, Ch 0–Ch 3) for monitoring device and channel status.

Terminal Area

• Power terminals
• Earth ground terminal
• 4 channel terminals (Channel 0–3) for connecting field instruments

5. Typical Applications

• Process Control: Connect pressure, temperature, and flow transmitters to host systems.
• Industrial Automation: Integrate HART instruments with Allen‑Bradley/Rockwell PLCs.
• SCADA Systems: Enable remote data acquisition and monitoring via DNP3.

6. Installation & Maintenance Recommendations

• Mounting: Use a DIN rail for secure installation and easy access.
• Power: Supply 24V DC and ensure proper grounding.
• Network Configuration: DHCP is enabled by default; use a static IP in control networks to avoid conflicts.
• Software Tools:
  • PLX50 Configuration Utility for IP and channel setup
  • Device Flash tool for firmware updates and backups
