MTT MS3727-A-A Slim Plug-In Signal Selector

The MTT MS3727-A-A is a slim, plug-in signal selector designed to switch between two input signals using switching contacts.

• Overview:
  • The MS3727 is a signal selector that allows you to choose between two input signals and output them using switching contacts.
  • It is available in three input types:
    • DC current input
    • DC voltage input
    • DC current input with a 50Ω shunt resistor.
• Specifications:
  • Power Supply Options:
    • A: AC 100~240V (50~60Hz)
    • D: DC 24V
    • P: DC 100~240V
  • Input Signals:
    • A: DC current signal
    • C: DC voltage signal
    • B: DC current signal (with a 50Ω shunt resistor)
  • Output Signal:
    • The output signal matches the level of the selected input signal.
    • For the DC current signal (with a 50Ω shunt resistor), it is the input signal multiplied by the shunt resistor (50Ω).
  • Switching Behavior:
    • When the power is ON and the switching input is ON, INPUT-1 is the output.
    • When the power is ON and the switching input is OFF, INPUT-2 is the output.
• Dimensions and Mounting:
  • Slim design: W29×H86×D125mm (including mounting screws and socket terminal).
  • Weight: Body 120g or less, socket terminal 80g or less.
  • Mounting options: Wall mount or DIN rail.
  • Wiring method: M3.5 screw terminal connection (with a cover to prevent detachment).
• Isolation and Environment:
  • Signal isolation:
    • Input/output to switching input: 2000V AC
    • Input/output to power/ground: 2000V AC
  • Operating temperature: -5°C to 55°C
  • Humidity: 5% to 90% RH (non-condensing)
