MTL831B Analogue Multiplexer Transmitter

MTL831B multiplexer transmitters are normally sited in the hazardous area. They are connected to sensors in the field and communicate

these inputs to the safe area via single-pair data highways. The data highways support communication between the safe and hazardous

areas,and also provide power to the transmitters – no additional field power is required.

The MTL831B would typically be mounted close to the field instruments in an enclosure such as the ENC8 or ENC83 

MTL831B ANALOGUE INPUT TRANSMITTER

Monitors inputs from up to 16 THC or millivolt sources (max ±60mV) or up to 15 2-, 3- or 4-wire RTDs within a hazardous area.

• Intrinsically safe; Zone 0 location

• Communication and power pass over twin data highways

• Powered by the data highway

• Thermocouples and RTDs may be mixed on one transmitter

MULTI-DROPPING TWO MTL831BS

Two MTL831B multiplexer transmitters can share the same single-pair highway to a single safe-area isolator/receiver combination, 

providing up to 32 multiplexed inputs.

DATA HIGHWAY CABLING

Cabling with low capacitance and resistance is recommended to achieve greater distances between transmitters and receivers. 

See cable parameters in 'Basic Specifications' for specific requirements, and contact MTL for latest cable recommendations. 

The system is designed to use both data highways, although it can be used with only one data highway in place. 

However, use of a single highway will increase response time. 

Data highway lengths of up to 2km in hazardous areas and 3km in safe areas have been achieved.

ENCLOSURES

A range of steel and stainless steel enclosures is available for mounting

MTL831B units in the field (see 'MTL800 Series Enclosures'). ENC8

and ENC8SS (stainless steel) enclosures provide protection for a

single MTL831B. The enclosures are dust-tight and waterproof to IP67.

When using 4-wire RTDs, ENC83 and ENC83SS (stainless steel)

enclosures provide additional terminals to accommodate the third and

fourth RTD wires, which are not connected to the MTL831B itself.
