Product Description:

The RZC01.1-5T-005-F-23 is a chemistry module produced by Bosch Rexroth Indramat as part of the RZC Chemistry Modules series. The unit forms an interface between drive power electronics and process instrumentation in automated chemical dosing or mixing equipment, providing regulated three-phase output and diagnostic feedback for repeatable fluid handling. By combining power handling with process-related signal connections, it suits fixed installations where pumps, agitators, and monitoring devices must operate together in a controlled sequence.

This module accepts a nominal supply of 3 x AC 500 V ±10 %, allowing operation on high-voltage industrial mains without an external transformer. Under that input, it delivers a steady output of 8.0 A, which is the continuous current available to downstream pumps, agitators, or metering drives. The output power capability is 4.0 kW, so loads within that range can be started and controlled without derating. Frequency conversion tops out at 100 Hz, allowing higher motor speeds when the connected process requires increased throughput. Environmental protection conforms to IP23, which helps shield internal components from accidental contact and from water spray in ventilated indoor areas. Internal circuitry uses filter current feedback to improve closed-loop accuracy, and the design and line identifiers 1-1 indicate the first build iteration within the series.

The housing is prepared for cabinet mounting, so it can be secured directly on a back plate in fixed control enclosures. An auxiliary supply described as external 24 V standby power keeps the control section active when the main supply is isolated, which helps retain status reporting and stored settings. Field connections are routed through a NAMUR terminal strip, making the module suitable for process signals commonly used with chemical sensing devices and switching components. Its Size Class A format helps reserve cabinet space and maintain consistent clearance around adjacent equipment.
