ABB NPCU-52C – Compact CPU Module

Description

ABB NPCU-52C – Compact CPU Module is a brand-specific industrial control CPU module designed for industrial automation applications. As a compact CPU unit, it falls under ABB’s industrial control product line, optimized for use in industrial control systems including distributed control systems (DCS). Based on general compact CPU module specifications from the same product category, this module is likely to feature a compact form factor suitable for space-constrained control cabinets. It may use RS-485 ports and USB-PPI cables for programming, as it does not include an Ethernet port. The module is expected to support up to 4 HMIs with PROFIBUS/RS-485 functionality, but does not support expansion signal boards or modules, memory cards, data logging, analog processing, high-speed pulse output, real-time clock, or motion control functions. It may offer up to 4 high-speed counters, with 4 single-phase counters operating at 100kHz and 2 A/B phase counters operating at 50kHz. Memory specifications are estimated to include 12KB program memory, 8KB user data memory, and 2KB non-volatile memory, providing sufficient capacity for basic industrial control logic and data storage.
