Product Description:

Bosch Rexroth Indramat manufactures the RZC01.2-5T-037-F-23 as part of the RZC Chemistry Modules series. The module is installed in chemical processing drive systems to supply regulated three-phase power and coordinate feedback signals that protect motors and field devices. As a chemistry module, it links the variable-speed drive section to higher-level controllers, allowing parameter adjustment and process-specific interlocks in automated production lines. This arrangement lets the drive system respond to changing process conditions while keeping power handling and signal supervision in one module.

The unit operates from a nominal supply of 3 x AC 500 V ±10%, which matches high-voltage plant distribution networks. At this input, it delivers a continuous current of 45 A and supports motor groups up to 30 kW without derating. Frequency conversion reaches 100 Hz, allowing connected drives to run motors above standard base speed when the application requires it. A protection rating of IP23 permits installation in controlled electrical rooms where falling water and large dust particles are limited. Because it is prepared for cabinet mounting, the housing aligns with standard enclosure rails and leaves clearance for heat dissipation. The unit is also assigned to design code 2 and line 1 within this product range.

An auxiliary input marked 24 V external standby power keeps the control electronics active during mains isolation, maintaining parameter memory and diagnostic logs. Field wiring is simplified by terminals supplied with a NAMUR terminal strip, which supports intrinsically safe sensor loops commonly used on dosing skids. The module is assigned to Size class C, which sets its cabinet width and height for layout planning. Filter current feedback is included as a secondary function and routes motor current data to the controller so phase imbalance or harmonic content can be corrected in real time under varying load conditions. The NAMUR connection format also helps the module fit process installations where low-energy field signals must be handled alongside drive control functions.
