Operator friendly Windows® based interface.

The PMII replaces existing PM96 control systems or can be installed new when manual controls are desired. The reliable Programmable Logic Controller (PLC) helps reduce control system downtime. PMII helps you meet or exceed state automation requirements while allowing flexibility for customization. This flexibility also allows the control system to be easily and cost-effectively upgraded as needs change. Optional remote PC control software allows diagnosis of control system problems via the internet (high speed internet access required).
