Overview

Essential details：MTL831B Multiplexers for Zone 0 hazardous area applications MTL

MTL830 Series multiplexers with Modbus® outputs provide a cost-effective alternative to single-loop isolation. The cost of installed wiring is reduced by up to 50% by communicating the input of multiple hazardous-area sensors over dual-redundant data highways. Further savings are achieved by reducing the number of inputs to the host, cabinet space and weight.
A multiplexer transmitter, mounted in the hazardous area, caters for thermocouple, RTD and mV analogue inputs. A compatible safe-area receiver provides serial Modbus® outputs for feeding to host PLC, PC or DCS controllers.
Dual-redundant data highways between the transmitter and the receiver allow continuous normal operation with only one highway connected. The highway cable, a simple twisted pair or a pair of wires within an IS multi-core cable, carries both power and data, over distances up to 2km. If the multiplexer transmitter is located in the hazardous area, each data highway must be protected by an MTL3052 digital isolator.

Multiplexer systems can communicate the status of up to 32 inputs, reducing the number of hazardous area wiring pairs from 32 to two. Reduce costs by eliminating long runs of expensive thermocouple compensation cable from the hazardous to the safe area. AIso, if 3- or 4-wire RTDs are used, costs are reduced by terminating each RTD at the transmitter or its enclosure.
Dual redundant highways increase system reliability. Failure detectors and safety drives protect against the consequences of sensor failure, while built-in systems report failures to the host controller.
Accessories include steel and stainless-steel enclosures, earth-leakage detectors and a PC-based configuration software package. For more information see AN9010, ‘A user’s guide to multiplexers’ and TP1098, ‘Cut the cost of intrinsic safety – by multiplexing!’

MTL831B

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 (see ‘MTL800 Series Enclosures’).
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.
