Product Description:

The RZC01.2-5T-018-F-54 chemistry module is manufactured by Bosch Rexroth Indramat and belongs to the RZC Chemistry Modules series. It is a dedicated power and signal interface used in automated chemical mixing, dosing, or neutralization skids. By combining three-phase power conversion with field sensor connectivity, the unit supplies controlled energy to process drives and channels feedback to a higher-level controller. This arrangement allows one module to support both motor actuation and process monitoring in sealed production equipment.

The module accepts a three-phase input of 3 x AC 500 V ±10% and routes it through an internal inverter that can deliver up to 15 kW to connected motors. Continuous phase current is limited to 24 A, so conductors and protective devices must match that load level. Frequency is adjustable from zero to 100 Hz, which allows variable-speed operation for pumps and mixers during process changes. That adjustment range supports smooth ramping where flow and agitation must be controlled without abrupt speed shifts. The housing has an IP54 protection class that helps shield internal electronics from dust and splashing liquids. The unit is Design 2 on Line 1, and the mechanical frame uses size class B for layout planning.

For panel installation, the unit is prepared for cabinet mounting, which simplifies alignment on standard rail systems inside enclosed panels. Control electronics remain powered by a separate external 24 V standby power feed, allowing diagnostics and network communication when the main supply is isolated. Field wiring is concentrated on a NAMUR terminal strip, which supports direct connection of intrinsic-safety proximity sensors used in chemical valves. This arrangement keeps low-level sensor circuits grouped away from the motor power section, which helps maintain signal clarity in cabinets with inverter switching. Measurement stability is supported by filtered current feedback, which reduces high-frequency noise so the automation controller receives steadier current data during variable-speed operation.
