Module MPU-1.01/02 is a replacement analog for multichannel control board MCB, which is a part of Stewart & Stevenson hydraulic fracturing complex control system.

MPC-1.01/02 module can be loaded with a firmware of one of four different types depending on the system purpose (automatic density controller, automatic chemical agents dosing controller, intelligent pump control system or additional data collection system).

MPU-1.01/02 is used in control panels for hydration unit, mixer unit, chemical agents dosing unit, hydraulic fracturing unit and data collection machine.
