MTL830B Temperature Multiplexer Transmitter
Eaton Crouse-Hinds MTL831B is the transmitter used in the earlier MTL830B temperature multiplexer system. Eaton transition guidance identifies thermocouple, millivolt and two-, three- or four-wire RTD channel configurations and notes that transmitter addresses 1 and 2 are set by switches. The manufacturer classifies the earlier MTL830B arrangement as obsolete and recommends an MTL831C, MTL5553 and MTL838C system solution. This is not a unit-for-unit substitution because the generations use different physical-layer technology. Procurement teams should capture the installed channel configuration, address, sensor wiring, isolator and receiver models, hazardous-area requirements and enclosure details before planning migration or maintenance.

Eaton lists the MTL830B arrangement under Earlier / Obsolete Products. Its recommended MTL830C-based solution is a complete-system migration, not a single-module drop-in replacement.
It identifies the transmitter used in the earlier Eaton MTL830B temperature multiplexer system.
Yes. Eaton lists the MTL830B arrangement under Earlier / Obsolete Products.
No. Eaton states that the transmitter, isolator and receiver solution must be replaced as a system.
Record thermocouple, millivolt and two-, three- or four-wire RTD channel assignments.
Verify sensor entity parameters, barriers or isolators, enclosure details and the approved installation design.
Yes. Request the front, terminal layout, address switches, nameplate and enclosure photographs.
