Integrated Power Supply & FBP Bus Expansion for ABB AC500 PLC Automation Systems
1. Core Product Overview
The ABB 500CSP04 (order codes: HE4013140002 / 1MRB150051R2) is an integrated communication and power supply module exclusively designed for the ABB AC500 PLC series, serving as a critical hub for system power distribution, FBP (Flexible Bus Protocol) bus expansion and auxiliary communication conversion in distributed automation systems. It integrates a high-stability industrial power supply unit and ABB’s proprietary FBP bus controller, providing reliable 24V DC power for AC500 I/O modules while enabling long-distance FBP bus expansion for distributed I/O deployment in large-scale industrial sites. With industrial-grade rugged design, it supports -20°C to +70°C operating temperature, IP20 front protection, and EMC/surge resistance, ensuring stable power supply and bus communication in harsh industrial environments such as chemical plants, power stations, metallurgy and water treatment systems. Fully compatible with all AC500 series CPUs (500CPU03/02/01) and I/O modules, it is a key component for building scalable AC500 PLC systems.

2. Industrial Power Supply Specifications
The 500CSP04 is equipped with a high-efficiency, low-ripple industrial switch power supply unit, designed for stable power distribution to AC500 I/O modules and field sensors. It supports 100-240V AC wide-range input (50/60Hz) with active PFC for high power factor, and outputs regulated 24V DC with rated current of 4A (max 5A peak), capable of powering up to 32 AC500 series I/O modules in a single FBP bus chain. The power supply unit integrates multi-level protection functions: overvoltage protection (28V DC cutoff), overcurrent protection (auto-recovery), short-circuit protection and thermal overload protection, effectively preventing damage to the module and connected I/O devices caused by power anomalies. It also supports optional 24V DC redundant power input, further improving the power supply reliability of critical industrial automation systems.

3. FBP Bus Expansion & Communication
The 500CSP04 is built with a high-speed ABB FBP bus controller, supporting both master and slave working modes for flexible AC500 system expansion. As a FBP bus relay/hub, it extends the maximum transmission distance of the FBP bus to 1000m (at 1Mbps baud rate) with RS485 physical layer, enabling distributed deployment of AC500 I/O modules in large industrial plants without signal attenuation. It supports auto-baud rate detection (125Kbps~1Mbps) and bus fault self-diagnosis, with front-panel LED indicators for real-time monitoring of FBP bus status (link/activity/fault). The module also provides an auxiliary RS485 communication port (Modbus RTU) for connection with third-party field devices, realizing data exchange between AC500 PLC and non-ABB industrial equipment. The FBP bus adopts channel-to-ground isolation (2.5kV) and EMC filtering, effectively resisting industrial electromagnetic interference and ensuring stable bus communication.
• FBP Bus: RS485 physical layer; 125Kbps~1Mbps auto-baud; max 1000m transmission distance; 2.5kV isolation
• Expansion Capacity: Max 32 AC500 I/O modules per bus chain; master/slave mode configurable; multi-bus chain support
• Auxiliary Communication: 1×RS485 port (Modbus RTU); multi-master/slave; 9600-115200bps baud rate
• Bus Diagnostics: Front-panel LED status indicators; bus fault self-diagnosis; fault alarm output; real-time bus activity monitoring
