MTL | MTL831B | Multiplexer Transmitter
SKU: MTL838B

  • Manufacturer: MTL

  • Product No.: MTL838B

  • Condition：In stock

  • Product Type: Multiplexer Transmitter

  • Product Origin: Britain

  • Payment:T/T, Western Union

  • Weight: 2000g

  • Shipping port: Xiamen

  • Warranty: 12 months

  • The MTL831B multiplexer transmitters are typically installed in the hazardous area. They connect to field sensors 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.

Installation

  • Usually mounted close to the field instruments in an enclosure such as the ENC8 or ENC83 (see 'MTL800 range of Enclosures').

Specifications

  • Number of Input Channels:
    • 16 THC or mV sources (potentiometer inputs up to 1kΩ)
    • 15 RTD or mixed
  • IS Segregation and Floating:
    • IS segregated and fully floating when used with MTL3052
  • Location:
    • Input Sources: Zone 0, IIC, T4
    • 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:
    • Working: –20 to +60°C
    • Storage: –40 to +80°C
  • Weight:
    • 1.3kg
  • Typical Response Time:
    • 1 second 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) 0.58µF, 127mH or 535µH/Ω
      • (IIB) 3.55µF, 486mH or 1087µH/Ω
      • (IIA) 14µF, 903mH or 1087µH/Ω
  • Electrical Safety (Data Highway Circuit[s]):
    • Umax:in = 30V
    • Imax:in = 300mA
    • Wmax:in = 1.2W
    • Ceq = 0, Leq = 0
