Product Description:

The RZC01.1-5T-022-V-23 is a Chemistry Module built by Bosch Rexroth Indramat within the RZC Chemistry Modules series. This unit acts as a power conversion and interface block for reagent dosing, pH control, and similar closed-loop tasks inside automated chemical-process skids. By conditioning three-phase supply power and forwarding discrete NAMUR sensor signals to the drive network, it streamlines motion and measurement channels for cabinet-mounted dosing pumps and agitators.

The module delivers a maximum output frequency of 100 Hz, allowing connected VFDs or servo stages to modulate pump speed over a wide control band. Input tolerance is maintained with a nominal supply of 3 × AC 500 V ±10 %, so the electronics remain stable even when plant mains fluctuate. Thermal and conductor sizing are matched to a rated current of 28 A, while the power section can continuously furnish 18.5 kW to downstream loads. A protection class of IP23 safeguards the enclosure against vertically dripping water and accidental finger contact during indoor operation. Because it is prepared for cabinet mounting, the chassis includes grounding studs and rail slots that allow direct installation inside a ventilated motor control center or control panel without extra brackets. The product is assigned to line 1 of the platform, which supports compatibility with first-generation RZC backplane connectors and signaling formats.

Field wiring is simplified by a NAMUR terminal strip arrangement that groups intrinsically safe I/O on a labeled block, reducing installation time in ATEX or Class I, Division 2 areas. The housing fits the footprint for Size Class C, so panel builders can reserve space consistently across projects. The mechanical layout follows Design 1, which standardizes bus bar spacing and cooling airflow for this revision.
