2 /6 osch Rexroth Corp. Industrial Hydraulics Model MDSD R 864/0.0 Functional description The MDSD is a high current amplifi er that controls proportional valves with one or two force solenoids. pplications lude the EL and EP controls on, 4,, pumps and 6 motors. lso luded are pressure and directional valves FT-DREK, DRE4K, DE, DET, MP, SM, SP, 4WR, 4WRZ. ll Volt solenoids can be controlled over the entire 0 to 8 VDC power supply range to simplify design. Of course, 4 Volt solenoids can be used in 4 Volt power systems. The rugged, compact design is environmentally protected by a potting compound (Concap: EN- Conathane). The MDSD has good insusceptibility to electromagnetic interference (EMI) and has a wide temperature range.
