ABB SA801F Power module

ABB SA801F Power module

Product core positioning

ABB SA801F is a high-precision power module designed specifically for industrial automation control systems, belonging to the core components of ABB Advance AC800F and FreeLance series control systems. Its core function is to provide stable power supply for the CPU motherboard, E1/E2 slots, and F1~F4 slot modules of the controller, and it is the "power heart" that ensures the continuous operation of PLC, DCS and other systems.

Key technical specifications

1. Power parameters

Input characteristics: Wide range AC input 115-230VAC (adaptive voltage), built-in EMC filtering function, can adapt to most industrial power grid environments worldwide; Some versions support dual power redundant inputs (DC9-36V, typical 24V) with power consumption below 4W

Output characteristics: Provides dual isolated DC outputs -3.3VDC ± 3%/5A and 5.0VDC ± 3%/5A, with a total output power of 26.5W and protective electrical isolation at the output end.

Endurance guarantee: In case of power failure, the output can be maintained for at least 20ms, meeting the requirements of NAMUR standard for power-off transition and avoiding data loss in the control system.

2. Physical and environmental parameters

Dimensions: The mainstream specifications are 132mm × 105mm × 52mm (some versions are 100mm × 50mm × 30mm), with a net weight of 0.46-0.8kg

Protection and installation: IP30 protection grade aluminum shell, supporting 35mm DIN rail installation, suitable for standardized layout of industrial control cabinets.

Environmental adaptation: Operating temperature range -10~70 ℃ (optional -40~85 ℃ wide temperature version), relative humidity ≤ 90% (no condensation), storage temperature -40~80 ℃.

3. Certification standards

Compliant with multiple international standards such as EN55022 (electromagnetic compatibility) and EN61000-4-2/3 (anti-interference), ensuring stable operation in complex industrial electromagnetic environments.

Core functions and security design

1. Multidimensional protection mechanism

Active monitoring: Real time monitoring of input/output voltage, with power failure signal output function, supporting early warning system for power supply abnormalities.

Fault protection: Integrated overcurrent limiting and short-circuit protection functions, with permanent short-circuit protection design at the output end to prevent damage to modules and load equipment.

Redundancy support: Some versions are equipped with a main/backup power switch, which can manually switch between primary/secondary circuits in redundancy mode to improve power supply reliability.

2. Diagnostic and operational features

Status indication: Real time feedback of working status through LED lights such as fault, run/stop, and main/backup power supply, facilitating quick troubleshooting.

Convenient maintenance: The modular design supports quick replacement of components, equipped with a received reset switch (tool operation required, anti misoperation), and the diagnostic interface uses a 9-pin Sub-D connector.

Calibration function: Supports two-point on-site calibration and can store ultra stable reference values in non-volatile memory, providing accurate calibration power for sensors such as thermocouples and RTDs.

Application scenarios and system adaptation

1. Core adaptation system

Main control system: designed specifically for ABB AC800F field controllers, compatible with CPU modules such as PM802F/PM803F, as well as components such as EI803F (I/O module) and TK807F (communication module).

Extended compatibility: It can be linked with industrial control components such as PLC, DCS, SIS (Safety Instrumented System), ESD (Emergency Shutdown System), etc., and supports Profibus DP V1 network communication.

2. Typical application areas

Covering heavy-duty industries such as electricity, petroleum, metallurgy, papermaking, and wastewater treatment, specific scenarios include:

Power supply for turbine/compressor unit control system (CCS)

Power supply for logic control units of port machinery and mine hoisting equipment

Power Support for Safety Instrumented Systems in Chemical Reactors and Metallurgical Blast Furnaces

Distributed control node power supply for municipal water supply and heating pipelines
