Product Description:

The RZC01.2-5T-037-F-54 is a chemistry module manufactured by Bosch Rexroth Indramat and assigned to the RZC Chemistry Modules series. Designed for automated chemical processing equipment, the unit forms part of the power and feedback chain that drives pumps, stirrers, and dosing stations. It sits between the plant’s three-phase mains and the motion or process controllers, conditioning supply energy and routing status signals so that reactions proceed under measured, repeatable conditions. By stabilizing incoming power and forwarding status information, it helps connected actuators respond consistently during mixing, transfer, and dosing steps.

The module accepts a nominal line supply of 3 x AC 500 V ±10% and generates a variable output up to 100 Hz, giving a speed-control range suitable for centrifugal pumps that handle viscous or volatile fluids. That adjustable output helps process equipment match motor speed to changes in flow demand and fluid behavior during operation. Under continuous duty, the power section delivers 45 A with a rated output of 30 kW. The enclosure is rated IP54, so it resists airborne dust and cleaning spray commonly found in process areas. The unit is Design 2 and Line 1, and it uses mounting holes and airflow paths intended for prepared control enclosures.

The enclosure belongs to Size Class C, which keeps the footprint moderate while leaving room for auxiliary boards such as the filter current feedback circuit that relays harmonic data to the drive controller. A dedicated input for 24 V standby power keeps diagnostic functions active when the main supply is isolated, allowing orderly shutdown and early fault detection. Field devices connect through a NAMUR terminal strip, enabling direct attachment of intrinsically safe sensors without extra isolators. This connection method supports low-energy sensor signaling in process equipment where stable status reporting is important during normal operation and controlled shutdown.
