Applications

  • Campus water, power management
  • Solar power
  • Remote monitoring of assets
  • Building Blocks
  • Remote I/O
  • Network
  • Central Unit with internet connectivity & display
  • Historian & HMI (optional)
  • Reports
  • Remote I/O
  • Example applications for these are Borewell / sump / overhead tank. These Remote I/Os are based on IIoT technology.
  • Accessories for Remote I/O
  • Auto/Manual stations: For each device such as motor or for group of Road lighting, this may be required.
  • In Manual, local start / stop buttons can be used. When in Auto motor start / stop will be from the Remote I/O.Position of Auto / Manual station can be monitored from Central Unit.
  • Relay interface: For contacts to be wired up with Auto/Manual stations or Motor starters, a relay interface has to be used with each Remote I/O unit. It can be in a separate enclosure or same enclosure with the Remote I/O unit, depending on the contact rating required.
  • Additional instrumentation: Flowmeter at discharge of pumps, Level measurement at sumps and overhead tanks, current meters, gen set status can all be connected to Remote I/O units.
...
  • Network
  • Wireless LAN adaptor: IIoT adaptor with Antenna. This is used for communication between Remote I/O and Central Unit.
  • Sometimes, when RF signal is weak, it is also used to form a bridge between two adaptors, like a wifi extender.



Central Unit

  • This is based on IIoT processors. For viewing over internet, internet connectivity is required. Local display can be connected via inbuilt HDMI interface.
  • Remote Monitoring
  • Motor Runing Status
  • Auto / manual switch position
  • Bore well discharge flow
  • Current indication etc
  • Remote Control
  • Motor on / off while in Auto, scheduled on / off,on / off of motors based on sump or OH tank level.
  • Scheduled Lighting on/ off
  • Equipment (motor, spray, heater etc) protection
  • Trip on low discharge.
  • Trip on high current
  • Trip on ambient conditions, etc
