MTL MTL831B is an intrinsic safety (IS) interface device from MTL Instruments for hazardous-area process loops. This HART multiplexer concentrates HART smart-instrument signals onto a single highway for central asset-management and configuration without disturbing the 4-20 mA loop.
| Parameter | Value |
|---|---|
| Channels | 32 |
| Protocols | HART 5/6/7, Modbus RTU, Modbus TCP |
| Connection | RS-485 or Ethernet |
| Power supply | 24 VDC |
| Approvals | ATEX, IECEx, FM |
| Mounting | DIN-rail |
Typical applications include oil & gas wellheads, chemical processing, coal-chemical plants and refinery instrumentation where a hazardous-area classification (Zone 0 / 1 / 2) requires intrinsic safety protection for 4-20 mA transmitters, solenoid valves and switch inputs.
