Building Blocks

Remote I/O


Central Unit with internet connectivity & display

Historian & HMI (optional)


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.


  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

  • Historian
