Exact Identification
Match MTL831B character by character and confirm the complete MTL831B Sixteen-Channel Analog Transmitter designation.
Interface Arrangement
Confirm the installed supply, ports, field connections and required accessories before wiring the replacement.
Configuration Check
Preserve the approved engineering project, network parameters and application data used by the installed system.
Product Overview
The MTL831B is a sixteen-channel field transmitter for thermocouple, RTD and millivolt signals in the MTL830B temperature multiplexer system, with two selectable addresses and dual data highways.
One transmitter accepts a mix of supported thermocouple, RTD and millivolt inputs according to its configuration. Two highways provide the documented field-to-receiver transmission path and status monitoring arrangement. Hazardous-area applications use an MTL3052 isolating interface on each data highway.

Frequently Asked Questions
Which sensors can I connect to MTL831B?
Configure the sixteen channels for the supported thermocouple, millivolt or RTD input types.
How do I set the field address on MTL831B?
Set SW100 switches 1 and 2 for address 1 or 2 as required by the existing system.
Does MTL831B require one or two data highways?
The transmitter provides two highways, and both should be wired and checked according to the installed architecture.
Which isolator is used with MTL831B in an intrinsically safe loop?
Use one MTL3052 isolating interface for each data highway in the documented system.
How far can MTL831B normally communicate in a hazardous-area installation?
The typical intrinsically safe transmission distance is 0.5 km within the specified highway conditions.
Can I replace only MTL831B with the newer MTL831C?
No; migration requires the transmitter, isolator, receiver and configuration software to be changed as a complete system.
What should I record before removing MTL831B?
Record every channel type and wiring, both highway connections, the SW100 address and the receiver configuration.
Compatibility & Ordering Notes
Compatibility Checklist
- Keep the transmitter paired with the MTL3052 and MTL838B generation.
- Do not mix MTL830B and MTL830C physical-layer components.
- Verify entity parameters and installation certificates for hazardous-area circuits.
