Product Description:

The RZC01.1-5T-011-V-23 is a Chemistry Module manufactured by Bosch Rexroth Indramat and positioned within the RZC Chemistry Modules series. Installed as part of an automated dosing or reaction skid, the device interfaces between higher-level controllers and field equipment that handle fluid flow, temperature, or pH adjustment. By converting control signals and switching power to pumps, valves, and sensors, the module helps maintain precise chemical conditions for repeatable industrial processing.

During operation, the module accepts a three-phase supply of 3 × AC 500 V ± 10 %, allowing it to remain stable even when plant voltage varies above or below nominal. Its power stage delivers up to 7.5 kW, and a continuous line draw of 14 A accompanies that rating, so feeder cables and breakers must support this current without nuisance trips. An adjustable carrier drives connected loads at frequencies up to 100 Hz, giving process pumps or agitators a speed range that extends beyond standard mains frequency. The housing carries an IP23 classification, which protects internal components from solid objects larger than 12 mm and from water sprayed at angles up to 60 degrees. Because of that enclosure level, the unit still requires sheltered placement inside plant cabinets.

The mechanical envelope is identified as Size Class B, giving the unit moderate height and depth so it lines up with adjacent drive modules on standard DIN rails or backplates. Factory drilling and slots provide cabinet mounting points, eliminating on-site machining and supporting the airflow pattern expected for convection cooling. For instrument loops, the built-in NAMUR-terminal strip offers segregated spring-clamp contacts that simplify intrinsically safe wiring and routine loop checks. Internal coding marked as Design 1 and the external designation line 1 identify this variant as part of the initial RZC release. This arrangement keeps the unit aligned with the intended control setup used in matching chemistry skids.
