Eaton MTL4850 SIL3 HART multiplexer
32-channel SIL3 HART multiplexer that links smart field devices to asset management systems without disturbing the 4–20 mA control loops.
- 32 HART channels per module with channel-to-channel isolation
- SIL3 certified to IEC 61508 – connects to safety loops
- Supports HART Rev. 5–7 devices with auto baud-rate detection
- Diagnostic LEDs and on-board event log
Overview
The MTL4850 is a compact, modular HART multiplexer for new and retrofit projects. It connects to smart field devices through termination boards, carriers and integrated backplanes, letting asset management systems read configuration, diagnostics and calibration data remotely without interrupting control signals.
Key features
- Self-contained structure with fixed capacity for repeatable performance
- Channel-to-channel isolation and isolated power supply
- Auto baud-rate detection, fault LEDs and event log
- SIL3 certified for connection to safety loops
Applications
Oil & gas, chemical and pharmaceutical plants; DCS/ESD systems that need centralised HART device management, including Zone 2 installations.
