NEW PLC tutorial and guides for automation

hi there, this blog is dedicated to provide you with PLC tutorial specifically for industrial automation and robotics.



There are two types of PLC available in the market, which is relay type and transistor type. the major difference between these two is the response time. The response for transistor type PLC can go as fast as 0.5 microsecs compared to those of relay types which have response time around 10 ~ 20 millisecs.

The ability of transistor type PLC to do fast switiching makes it possible for it to have pulse outputs and high speed input to control AC servo motor.
