Foundation by Franz SorgDevelopment and production of first electronic controllers for screw air compressors
1975 - 1980:
Electronics for electric motors: U1, U2, U3, U4: programmable star-delta time, programmable follow-up time, LED indication of warnings and faults
Move out of our home garage to our first company production facility. At this time R-S-I has 5 employees.
SSR: „start-stop relay” electronics for diesel driven compressors
Development of our first electronic controller for water treatment systems
New generation of controllers: PLCs MK 1, MK 2, MK 6
Introduction of the first microprocessor based compressor controller
new modular PLC: E 85
Move to a new corporate design and production facility (1200 sqm) in Schweitenkirchen / Germany.
R-S-I now has 30 employees.
Implementation of SMD technologies for PCB production
and processing of analog signals on controller units
Expansion of production facility by 1000 sqm (total 2200 sqm)
Expansion in the German air compressor and water treatment market. Co-operation with leading manufacturers
First sequencer for air compressor stations
First customized display for our air compressor controllers
1993 - 1995:
New generation of compact control: K 10, MK 10, MK 100
Development of electronic controllers for pressure maintenance systems in heating systems.
Own line of field bus couplers: Profibus, Modbus, CAN
Flash programmable microcontrol. Field download of controller programs possible (software update)
Teleservice solution for compressor controllers; visualization software for compressor plants
First graphic display for controllers
Expansion of production and design facility to 3000 sqm and improvement of factory automation for advanced PCB manufacturing.
First controllers for speed regulated compressors with frequency converters
New generation of compact controllers: MK 20 GR, MK 20 CM, MK 200-K and TAN GR 128; air compressor plant simulation for testing of sequencers;
electronic controller with advanced sensor integration on board pressure sensor and onboard fan motor monitoring
Compact controller MK 15: integration of onboard pressure sensor
Start of development of web services for controllers
Development and production of automative controllers
Start of development of electronic controllers for wood burning heatings
New generation of controllers: introduction of color graphic displays (up to 7 inch) and resistive touch
Expansion of production facility to 4000 sqm
Cooperation with UX Design agencies
New platform (Linux based) for operating panel with integrated webserver. First use: heating applications.
New platform is used for development of a new generation of compact compressor controllers.
40th anniversary of RSI in Schweitenkirchen!
