HIMA B5232 (H51q-H/HR System Rack)

The B5232 is a 19-inch 5U high-availability safety system rack from the German HIMA (HIMAT) H51q series. It is divided into two models: **B5232-1 (Single Bus H51q-H) and B5232-2 (Redundant Bus H51q-HR)**. It is designed for medium-sized SIS/ESD/BMS systems and offers higher I/O capacity and bus redundancy capabilities.
