  • DIN rail mountable.
  • Provides N/O (normally open) and N/C (normally closed) contacts for each output.
  • Available as either 12 or 24VDC (DIN mounted power supplies available stock codes A10010 12VDC or A10055 24VDC)
  • Connects into an I/O module on a R400 Series indicator (prewired cable available supplied separately stock code M4902


DIN Rail Mounting Power Supply (12 or 24V DC)

  • 110-240V AC to 24V DC 2A output
  • DIN rail mountable switch mode power supply

 Converter for Analog Input (M4903)

The M4903 connects into the load cell input on an R400 Series Indicator to create an analog input (0-10V or 4-20mV input) into the indicator  for use with sensors that generate a 0-10V or 4-20mV output - for example force or pressure transducers.
