Product Description:

The RZC01.1-6T-045-V-23 chemistry module is produced by Bosch Rexroth Indramat within the RZC Chemistry Modules series. It is intended for integration into automated chemical dosing or surface-treatment lines where controlled power delivery and signal interfacing are required. Acting as a dedicated power stage, the unit links upstream drive electronics with pumps, agitators, or electrolysis cells, allowing the higher-level controller to regulate current and frequency supplied to process equipment. The module’s configuration supports standard cabinet installation practices used in large-scale industrial automation cabinets.

Its maximum output frequency reaches 200 Hz, giving the host controller a broad modulation range for inductive or resistive loads used in chemical applications. The power section is rated for a three-phase supply of 3 × AC 400 V ±15 %, permitting stable operation on typical plant mains even when voltage fluctuates. At nominal conditions, the module provides a continuous output current of 68 A, corresponding to a thermal output capability of 37 kW. The enclosure has IP23 protection, so the unit must be mounted in a sheltered electrical enclosure. Mechanical integration is simplified because the housing is prepared for cabinet mounting, allowing direct fastening to backplanes or DIN rails without additional brackets.

The module is built in Size Class C, which sets the footprint and clearance required inside the control cabinet and matches the auxiliary busbars used for that class. Field wiring is expedited by a front-side connection strip that is supplied with a NAMUR terminal strip, and this standardized layout separates intrinsically safe signal lines from power conductors during installation. The hardware belongs to Design 1 of line 1, which uses the baseline component placement and cooling path found in early RZC modules.
