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
