I want to know the number of input/output points for the SA350 multipurpose controller.

SA350 (Information Section) and SA350-IF (Input/Output Section)

The multi-purpose monitoring controller has an information section and an input/output section, each with an input/output interface.

Digital Input

SA350(Information Section)

  • Non-voltage contact input, power failure compensation input 4 points
  • Power failure (power abnormality), surge arrester failure, door open/close signal, spare input (4 points)

SA350-IF(Input/Output Section)

  • 16 non-voltage contact inputs
  • Switchable to 4 device operation inputs, 2 pulse integration inputs

Digital Output

SA350

  • 4 a-contact outputs that can turn AC250V/0.5A on/off
    • (Fan, heater, water level output 2 points)

SA350-IF

  • 4 a-contact outputs that can turn AC250V/0.5A on/off (remote control output)

Analog Input

SA350-IF (Input/Output Section): 5 points

  • 2 two-wire water level gauge inputs
    • (Can be switched to 4-20mA by changing wiring. With 10-point broken line approximation function. With analog pulse conversion/integration function)
  • 1 0-5V voltage input
  • 2 operating current inputs (100A/300A range switchable by setting)
