Programmable Relay

Programmable Relay is a device that control logics as PLC, but it has limitations. This gives small number of input outputs and don’t have many functions as PLC. This is very useful in small applications. The main feature that programmable relay has is it has real calendar. So is can set to function using calendar. We used OMRON ZEN-10C1DR-D programmable relay in our training. It can program on the device, it has supplied a small display that can write the ladder diagram and run it.

Inverter


Inverter is a device that can control a 3phase induction motor in many ways. Within a very little period I learnt have to quick read the manuals and get the maximum usage of the device. As example driving foreword & reverse, electronic starting method, range of rpm, adjustable acceleration functions and adjustable breaking functions. I could drive a 3phase induction motor many ways that our engineer needs
