FIELD INSTRUMENTATION / SIGNAL INTERFACE
PLX51-HART-4O
4-Channel HART Output Module
Connect HART-compatible field equipment, including valve positioners, to supported industrial Ethernet networks. The module combines four-channel HART communication with analog 4–20 mA signals, allowing process values and HART device communication to work within an appropriate control architecture.
|
FIELD SIGNAL PATH
Choose the network mode and device topology according to the intended controller architecture.
|
| 01 / HART & Analog | Four HART communication channels support analog 4–20 mA signals for compatible field devices. Typical use includes connecting valve positioners and exchanging process-related data through the supported network interface. |
| 02 / Network Modes | Supports EtherNet/IP, Modbus TCP/IP and DNP3 over TCP/UDP. EtherNet/IP supports direct integration of HART devices into a compatible Rockwell Automation Logix I/O tree. Point-to-multipoint operation is supported for EtherNet/IP with up to five devices; confirm the required topology before installation. |
| 03 / Electrical & Physical | Supply range: 12–28 VDC. Enclosure rating: IP20, NEMA/UL Open Type. Operating temperature: −20°C to 70°C. Dimensions (H × W × D): 101 × 22.5 × 120 mm. Power demand depends on the attached field devices. |
| MODEL | CORE FUNCTION | SELECTION ADVANTAGE |
| PLX51-HART-4O | Four-channel HART output and 4–20 mA signal integration | Best suited when HART-compatible field equipment must connect to supported Ethernet protocols. |
| PLX31-MBTCP-MBS4 | Modbus TCP/IP to four-port Modbus serial | Better suited to installations with existing serial Modbus instruments and multiple serial branches. |
| PLX32-EIP-MBTCP-UA | EtherNet/IP + Modbus TCP/IP + OPC UA Server | Designed for multi-protocol data exchange when OPC UA client access is part of the application. |

|
| Q1. Can PLX51-HART-4O connect HART valve positioners to an Ethernet-based controller? | Yes. It is intended for HART-compatible field devices such as valve positioners and supports EtherNet/IP, Modbus TCP/IP and DNP3 Ethernet connectivity. Confirm the required protocol, device mode and controller integration method before ordering. |
| Q2. What should be checked when replacing PLX51-HART-4O with another HART module? | Match the number of HART channels, 4–20 mA signal requirements, protocol, field-device topology, supply voltage, terminal wiring and controller configuration. A four-channel HART output module is not automatically interchangeable with a HART input module. |
| Q3. Does PLX51-HART-4O support point-to-multipoint communication? | Point-to-multipoint is supported for EtherNet/IP with a maximum of five devices. Point-to-point network operation is supported with EtherNet/IP, Modbus TCP/IP or DNP3 over TCP/UDP. Confirm the intended arrangement and field-device compatibility. |
| Q4. What power supply and installation conditions does PLX51-HART-4O require? | The module requires 12–28 VDC and has an IP20, NEMA/UL Open Type enclosure. Its operating temperature range is −20°C to 70°C. Allow for the additional power demand of connected field devices and install it within a suitable protected enclosure. |
| Q5. What information helps confirm PLX51-HART-4O availability and application fit? | Provide the full part number, quantity, destination, target delivery date, controller platform, selected Ethernet protocol and the number/type of HART field devices. This helps verify whether the requested model fits the intended network arrangement. |
