The GRACO 24H372 ACS Module is a control module designed to provide optimal analog drive signals to variable frequency drives (VFDs) for E-Flo circulation pumps. It is constructed with electronic components and is intended for use in paint and fluid circulation systems to enable flow and pressure control.

Key Features:

• Control Module
• ACS Module (24H372)
• Electronic components, DIN rail mountable
• E-Flo circulation pumps (Series D and later; for Series C and earlier, check with distributor)
• Provides analog output (2 × 4-20 mA) for VFD communication
• Digital outputs (2 × 1A, 24 VDC, open contact, normally open relay) for back pressure regulator and drive enable
• Ethernet and RS485 communication ports
• Operating temperature: 0–50°C (32–121°F)
• Operating humidity: 10–90% RH, non-condensing
• Designed for non-hazardous installation locations
• DIN rail mounting for easy integration

Applications:
Used in paint and fluid circulation systems to control E-Flo pumps, enabling precise flow and pressure management in industrial environments.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the circulation system.
• Verify that the 24J305 Sensor Circuit Kit is installed on your E-Flo Pump (Series D and later) for full functionality
• Use the 16D612 Power Module Assembly to supply 24 VDC to the sensor circuit
• Mount the ACS Module on a DIN rail in a non-hazardous location
• Follow all wiring and safety instructions in the GRACO manual
• For Series C and earlier pumps, consult your local GRACO distributor for compatibility
• Regularly inspect wiring and connections
• Ensure the module is kept within specified temperature and humidity ranges
• Refer to the GRACO manual for troubleshooting and maintenance procedures
