Series:Control System

  Product Description

  The P 44713A is a 24 channel high-speed FET multiplexer that can directly multiplex voltage,resistors,thermocouples,and strain gauges.44713A maximizes measurement throughput and improves system reliability.

  High switching speed:5500 channels per second on the backplane,100000 channels per second on ribbon cables

  Up to six(eight with extenders)high-speed FET multiplexers can be controlled through ribbon cables

  The 24 channel multiplexer only switches between high and low levels.Each floating input is balanced(with equal impedance between high to chassis and low to chassis)to provide good common mode suppression

  FET has no mechanical limitations as it will not wear due to switches

  Large input voltage:Rear and back panel input protection to 16 V peak.When the analog backplane is disconnected from the multiplexer,the backplane voltage can reach a peak of 42 V

  Large input current:1 mA per channel

  Input impedance

  Power on resistance:>10 8Ω

  Breaking resistance at Vin 10 V:>1000Ω

  Vin>Power off resistance at 10 V:>200Ω

  Large capacitance at 1 MHz:200 pF

  Closed channel path resistance:3.1 kΩ

  Bandwidth:1.0%flatness at 20 kHz,-3 dB bandwidth at 200 kHz

  Crosstalk:-50 dB at 10 kHz,-35 dB at 100 kHz

  Large offset voltage:15?V at 0 to 28°C,185?V at 28 to 55°C

  Large bias current

  When the isolation relay is closed,high or low current flows from the chassis into the input terminal or backplane:±5 nA DC at 0 to 28°C and±45 nA DC at 28 to 55°C

  When the isolation relay is turned on,high or low current flows from the chassis into the backplane:±1 nA DC at 0 to 55°C

  Large wire size:16 AWG

  Reference end compensation accuracy:0.1°C

  Isothermal module with large temperature difference:0.2°C
