8 Channel HART® Input Module
PLX51-HART-8I
The PLX51-HART-8I supports the interfacing of HART devices on each of the 8 analog HART channels with either EtherNet/IP™ (Target or Originator) or Modbus Client/Server (TCP, RTU232, RTU485) protocols. Each channel supports both voltage and current input options (e.g., 4-20mA, Voltage, etc.), with or without HART communication enabled.
The PLX51-HART-8I supports up to 8 HART devices per channel (multidrop).

特性 优势
- HART Input Channels: Supports 8 isolated HART input channels, accommodating up to 8 HART devices per channel, for a total of 64 HART devices.
- Communication Interfaces: Operates with EtherNet/IP (target or originator) and Modbus TCP, RTU232, or RTU485 (client or server).
- Custom HART Commands: Allows for custom acyclic HART commands to all connected HART devices.
- Analog Input Options: Supports various analog input ranges including 0-20mA, 4-20mA, 0-10Vdc, and 0-20mA or 4-20mA with an external resistor.
- Network Redundancy: Equipped with dual Ethernet ports for Linear or Device-Level-Ring (DLR) topology.
- Simplified Configuration: Facilitates easier setup and configuration through auto-generated .L5X files that can be imported into the controller.
