Product Description
Product Overview
The ABB PM904F 3BDH001002R0001 CPU Module is a high-end base unit within ABB’s Freelance AC 900F controller family, designed for advanced industrial automation applications. Featuring an 800 MHz CPU clock, 48 MB of controller memory (16 MB battery-buffered SRAM and 32 MB DRAM), and four Ethernet interfaces, this module supports up to approximately 1,500 I/Os depending on the application. It includes four slots for assembling Communication Interface Modules and requires an external 24 V DC power supply. Measuring 285 x 152 x 95 mm and weighing 1.1 kg (2.43 lb), it is supplied without an operating system (requiring software version 2019 or higher) or included display unit (TD 951F) and battery (TA 951F). Compliant with RoHS Directive 2011/65/EU and WEEE standards, it is a robust, scalable solution for distributed control systems.
