Remote On/Off Controller for AC Motors With Parameter Monitoring This project aims to use the keyboard for switching Electrical Motors etc. Also we can monitor the Current for the devices. This project also has the provision for setting the current limit also, and the loads will get tripped if the current exceeds the limit. The Actions Done is indicated using the LEDs on/off. This is achieved with the use of advanced Transducers and Relays. The is e o/p of the sensors is conditioned and displayed on the LCD Dsisplay. The Features included are On/Off provision for Devices: Using keyboard we can able to Switch on or switch off the Motors by using the Keys. The indications are given in the LEDs., Status of the devices (On or Off).

1. Remote On/Off Controller for AC Motors With
Parameter Monitoring
This project aims to use the keyboard for switching Electrical Motors etc.
Also we can monitor the Current for the devices. This project also has the
provision for setting the current limit also, and the loads will get tripped if the
current exceeds the limit. The Actions Done is indicated using the LEDs on/off.
This is achieved with the use of advanced Transducers and Relays. The is e o/p of
the sensors is conditioned and displayed on the LCD Dsisplay. The Features
included are
On/Off provision for Devices:
Using keyboard we can able to Switch on or switch off the Motors by
using the Keys. The indications are given in the LEDs., Status of the devices
(On or Off).
Temperature based Action:
By using thermistors we can able to identify the temperature fo the devices
and we can accordingly trip the devices.
Demonstration Purpose we use pulp load instead off AC Motor
