MTL831B

serial-data outputs

Analogue inputs to controllers with Modbus® communications

Redundant data highways

MTL831B MULTIPLEXER TRANSMITTER

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

MTL831B (mV input)

Number of input channels 16 THC or mV sources, potentiometer inputs up to 1k?)

15 (RTD or mixed)

(IS segregated and fully floating when used with MTL3052) Location of input sources Zone 0, IIC, T4

Location of unit Zone 0, IIC, T4

Number of data highways Dual redundant (either or both)

Power requirement Loop-powered through data highway from receiver

No hazardous-area power supply required

Multi-transmitter facility 1 or 2

Ambient temperature limits –20 to +60°C working, –40 to +80°C storage

Typical response time 1s for each transmitter (input to receiver output)

Electrical safety (each input circuit) Umax:out = 15V

Imax:out = 16.3mA

Wmax:out = 60mW

Input sensor cable parameters

BASEEFA values (C,L or L/R)

(IIC) 0.58?F,127mH or 535?H/?

(IIB) 3.55?F, 486mH or 1087?H/?

(IIA) 14?F, 903mH or 1087?H/?

Electrical safety (data highwaycircuit[s]) Umax:in = 30V

maximum input parameters Imax:in = 300mA / Wmax:in = 1.2W / Ceq = 0, Leq = 0
