Power module 6FC5203-0AF06-1AA0 Siemens terminal module

Description

Siemens’ 6FC5203-0AF06-1AA0 power module is a terminal power module designed specifically for SIMATIC S7-1500 series PLCs, mainly used to provide stable 24V DC power for distributed I/O devices (such as ET200MP) or expansion modules.
Core parameters and technical specifications
INPUT VOLTAGE
Rated value: 24V DC (typical industrial power supply voltage).
Allowable range: 20.4-28.8V DC (wide voltage design, adaptable to power supply fluctuations).
output power
Maximum value: 240W (supports high load requirements, such as driving multiple I/O modules).
Output current: 10A (at 24V DC).
Protection function
Overvoltage protection: automatically cuts off output to protect downstream equipment.
Short circuit protection: Built in fuse mechanism to prevent module damage.
Overtemperature protection: Monitor the temperature of the module and operate or shut down in case of overheating.
status indicator
LED indicator light: displays the power status (green=normal, red=fault).
Diagnostic interface: Supports reading module status through PLC (requires configuration).
mechanical properties
Installation method: rail installation (compliant with DIN EN 50022).
Protection level: IP20 (indoor use), it is recommended to install a protective cover for harsh environments.
Dimensions: Approximately 120mm (width) x 130mm (height) x 60mm (depth).
Typical application scenarios
Distributed I/O power supply
Provide power supply for ET200MP distributed I/O station, supporting remote signal acquisition and control.
PLC expansion module power supply
Drive the communication module and digital/analog module of S7-1500 system.
rps
Parallel connection with redundant power modules to enhance system reliability (requires configuration of a redundancy manager).
User core focus points
compatibility
Only compatible with Siemens S7-1500 series PLC and specified expansion modules (such as SM1234 digital module).
Hardware configuration and parameter settings need to be done through TIA Portal software.
Redundant design
Support parallel redundancy (requires configuration of 6FC5203-0AF06-1AA0 × 2+redundant modules).
In redundant mode, seamless switching in case of single module failure ensures continuous system operation.
Scalability
Multiple power modules can be connected in parallel (up to 4), with a total output power of 960W.
Attention should be paid to the power bus current limit (recommended total current ≤ 40A).
Diagnosis and Maintenance
Access module status through PLC program or web server (Profinet communication needs to be enabled).
Regularly clean the heat dissipation holes to avoid dust accumulation and overheating.
Alternative and upgrade suggestions
Alternative model: If higher power is required, 6FC5203-0AF06-1AA1 (480W output) can be selected.
Functional upgrade: Consider integrating a power management module (such as 6EP1961-3BA21) that supports energy efficiency monitoring and remote restart.
Communication extension: Add Profinet interface module to achieve networked monitoring of power status.
