4 Channel HART Output Module
PLX51-HART-4O
The PLX51-HART-4O allows users to easily connect their existing HART-compatible field devices to EtherNet/IP™, Modbus® TCP/IP, and DNP3 Ethernet networks.
The module can be used to connect HART Output devices such as valve positioners into an Ethernet network. The PLX51-HART-4O supports up to 4 channels of HART communication, as well as Analog 4-20 mA signals for real-time process variables to/from the HART-compatible device.

Features and Benefits
- Support for point-to-multipoint network, maximum of 5 devices (EtherNet/IP only)
- Support for point-to-point networks with EtherNet/IP, Modbus TCP/IP or DNP3 (TCP/UDP) protocols
- EtherNet/IP enables a HART device to be added directly into a Rockwell Automation® Logix I/O tree
- Modbus TCP/IP enables a HART field device to be viewed as a Modbus Slave device
- DNP3 converts a HART field device into a DNP3 Outstation (slave) supporting Secure Authentication
- DTM (Device Type Manager) / HART Pass-through is available for further simplifying device configuration and management using an FDT frame
- Built-in Web server provides detailed diagnostics of system configuration and operation as well as field device diagnostics
- Can be used in a redundant ControlLogix® controller system
- Advanced Diagnostics automatically extracted and written to Logix Tags
