The modular servo system enables students to study the theory and practice of automatic control systems. It illustrates modern circuitand constructional techniques.The system is modular and, therefore, versatile. Each unitis fitted with a magnetic base which holds the unit to the plastic coated steel base plate, irrespective of the angle at which the base plate is positioned. Individual units may be so arranged to create operating block schematic systems and interconnections between the units are made by jumper leads terminated in 4 mm stackable plugs. The modular concept of the MS150 system permits the study of individual units and also, by combination, the investigation and performance testing of complete systems. A series of instructional manuals is supplied to provide comprehensive coverage of servo system theory and assignments.

The equipment set incorporates student experiments which can be carried out in a laboratory safely using safety extra-low voltage. Experiment instructions are contained in a manual in either printed or digital form.
