b) Opto-isolated Input.

The use of opto-isolated input is a switch operated. Operate to enable

TLP 181, the input must be between the range of 3V to 30V (Screw terminal

blocks M2, M3). If put in the opto-isolated voltage does not meet the prescribed

range, the TLP181 is not to operate. These applications can be seen more clearly

by further explanation. As an input to the Opto-Isolated reaches 3V TLP 181 will

operate and cause the transistor to send data to the microcontroller. Enter the

micro controller will receive a logic 1 (ON) if TLP181 operate and will receive a

logic 0 (OFF) if the input opto-Isolated input is less than 3V or greater than 30V

[3].

c) MOSFET Outputs

MOSFETs are used both as discrete devices and as active elements in

digital and analog monolithic integrated circuits. in this circuit, MOSFETs

output should be connected to screw terminal blocks M6 and M7. MOSFET can
