NodeXS3

The NodeXS3 is a robust industrial automation node with protected inputs and outputs. It can be configured for numerous applications where a small number of analogue or digital inputs are required, and where the unit is positioned remotely. The four analogue inputs may be used to measure varying inputs with 12-bit accuracy. The six digital inputs are optically isolated and can detect pulses ranging from 5VDC to 220VAC. It also includes a low power counter on digital input one to count pulses for storage and periodic uploads. Primary communication is provided by a Lora Communication module which also includes SIGFOX, WIFI and BLE communication. The unit can be powered from high DC voltages (42VDC) and has an advanced battery charger with power point tracking. In addition it can power external sensors up to 14VDC to take measurements. It also includes three relays rated at 30VDC/220VAC/16A to control external devices.

Applications

  • Water reservoir level monitoring (4x reservoirs)
  • Water flow counter (1x low power counter, 5x normal)
  • Process output counter
  • Security (dry contact/movement)
  • Alarm trigger (dry contact/siren/warning light)
