2702321 Phoenix Contact – Ethernet HART multiplexer – GW PL ETH/BASIC-BUS
Modular gateway Ethernet head station with Modbus TCP, HART IP, FDT/DTM. Supports five expansion modules.
Description
The 2702321 is an Ethernet HART multiplexer from Phoenix Contact, designed for industrial automation and process control applications. It serves as a protocol gateway, enabling seamless communication between HART-enabled field devices (e.g., smart transmitters, flow meters) and Ethernet/IP networks1.
Key Features:
-
Protocol Support:
- HART Protocol (for legacy 4-20mA devices) and Ethernet/IP (for modern industrial networks)1.
- Acts as a HART-to-Ethernet bridge, facilitating IIoT and SCADA integration1.
-
Connectivity:
- RJ45 Ethernet port (10/100 Mbps) for network connectivity.
- HART bus interface for connecting up to 8 field devices (similar to 2702235)2.
-
Industrial Durability:
- -40°C to +70°C operating temperature range.
- DIN-rail mountable for control cabinet installation1.
Typical Applications:
- Process Automation:
- Integrates HART instruments (e.g., pressure sensors, temperature transmitters) into Ethernet-based control systems1.
- Remote Monitoring:
- Enables real-time data collection from field devices via Ethernet/IP1.
