ABB 500CPU03 1HDF700003R5122 CPU Module

Series Affiliation: Central Processing Unit (CPU) module of ABB AC 500 series PLC, serving as the core control unit of the system. It is responsible for executing user programs, processing input/output signals, and coordinating communication between modules.

Core Functions: Supports logic control, data computation, motion control, and communication management. Suitable for medium to large industrial automation systems, such as production line control, process automation, and mechanical equipment scenarios.

Processor: 32-bit high-performance microprocessor with a main frequency ≥100MHz, supporting floating-point operations.

Memory:

I/O Expansion Capability: Can connect up to 128 I/O modules, supporting distributed expansion (connecting remote I/O via communication modules).

Integrated Interfaces:

Protocol Support:

Scan cycle: ≤0.1ms/K instruction (basic logic instructions), suitable for high-speed control scenarios.

Real-time performance: Supports hardware interrupts (response time ≤100μs), meeting emergency signal processing requirements.

Storage expansion: Supports SD cards (up to 32GB) for program backup and data log storage.

Power supply: 24VDC (±20%), power consumption ≤15W.

Isolation: Electrical isolation between power supply and I/O (1500V AC/1min), with strong anti-interference capability.

Mounting method: 35mm DIN rail mounting, supports vertical/horizontal installation.

Operating temperature: -25°C–+60°C, humidity 5%–95% (non-condensing).

Sequential control of automobile production lines and collaborative control of robots.

Motion control of packaging machinery (such as speed regulation and positioning of servo motors).

Analog regulation in chemical and power industries (such as temperature and pressure PID control).

Logic control and data acquisition for pump stations and water treatment systems.

Communicates with SCADA systems (such as Wonderware, WinCC) via Ethernet interfaces to achieve remote monitoring.

Connects remote I/O modules (such as ABB 500I/O series) as a master station to build distributed control systems.

Ethernet interface: Labeled as ETH, supporting 10/100Mbps auto-negotiation, can connect to switches or upper computers.

Serial port: DB9 interface, default RS-485 mode (half-duplex), can be configured as RS-232 (full-duplex) via software.

Programming interface: USB interface (Type-B) for connecting to programming computers (using ABB Control Builder software).

Expansion interface: Backplane bus interface for connecting I/O modules and communication modules (such as 500CMP04).

RS-485 wiring:

Programming software: Use ABB Control Builder AC 500, supporting IEC 61131-3 programming languages:
