Key Characteristics
RH923DD baseplate provides passive backplane bus connection, supporting hot-plug-in installation of FPS400-24 power unit and multiple FBM fieldbus I/O modules.
FPS400-24 power module features built-in power-factor correction for improved grid-side performance, typical conversion efficiency reaches 92 % under 230 V AC full-load condition.
Adopts dual-stage current-limiting protection, overvoltage shutdown circuit and transformer-galvanic-isolated 24 V DC output to avoid fault propagation between mains and control side.
Approved for installation in Class 1 Division 2 and ATEX Zone 2 hazardous locations, suitable for non-incendive industrial cabinet application.
Operating ambient temperature ranges from -30 °C to +71 °C; storage temperature spans -40 °C to +85 °C; non-condensing relative humidity 5 %-95 %.
Ingress protection rating IP20, designed exclusively for indoor control-cabinet mounting.
Front-panel LED status indicators visualize power-good, fault and alarm conditions for fast-onsite diagnostic and maintenance work.
Certified by UL, CSA and CENELEC; strictly validated by Foxboro for native compatibility with 200-Series Fieldbus Modules without extra adaptation.
Supports redundant power-supply configuration on RH923DD baseplate to enhance overall DCS subsystem availability for non-stop process production.
Screw-type terminal blocks offer reliable mains-input wiring, built-in filtering suppresses industrial-site surge and electromagnetic interference.
