Double output temperature control system.
3-phase SCR zero crossing/phase shifting control system.
It is used for cascade control system.
It is is also used in Position-proportion control system etc.
PID Controller provides reasonable control of most industrial process, provided that the performance demand is not too high.
PI control are generally adequate when plant or process dynamics are essentially of First order.
Integrated System- It use Channel Architecture technology to unify signal flow from sensors to software for large systems.
