NiYo Engineers’ PLC Based Boiler Firing Sequence Simulator helps understand the basic principles of boiler firing sequence and PLC programming. All the inputs and outputs are optically isolated to protect the PLC from electrical spikes.

A large mimic diagram helps understand the system easily. For better understanding, instructor can introduce predefined faults in the system. Trainees then go through logical process of fault finding. Six different faults can be introduced.

Additionally, one can get good experience of PLC programming.
