Custom Build PLC Controlled Panels

Sai Automation  offer  automatic PLC Controlled panel as per requirement  of customer for pipe and tube production.  Programmable logic controllers (PLC) Controlled panel  are easy to operate and possess salient features such as digital and analog inputs, relay output, timers, counters, time switches, and auxiliary relays. 
PLC are designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery-backed-up or non-volatile memory.

Before the PLC, control, sequencing, and safety interlock logic for manufacturing was accomplished using hundreds or thousands of relays, cam timers drum sequencers, and dedicated closed-loop controllers. The process for updating such facilities for the yearly model change-over was very time consuming and expensive, as electricians needed to individually rewire each and every relay.

Early PLCs were designed to replace relay logic systems. These PLCs were programmed in "ladder logic", which strongly resembles a schematic diagram of relay logic. This program notation was chosen to reduce training demands for the existing technicians. Other early PLCs used a form of instruction list programming, based on a stack-based logic solver.
