        Features:

        • One module works with DC power supplies or AC mains; reduces spare part inventory.
        • Fast fuse (5x20 mm, 10 A) is user‑replaceable; green FSG LED indicates fuse OK; red SF LED indicates group error.
        • Narrow form factor saves cabinet space; clear derating curves for current vs. temperature (10A DC down to 7A at 60°C; 8A AC down to 5A at 60°C).
        The 6ES7138-4CB11-0AB0 is one of the most versatile power modules in the ET 200S family. It accepts a wide range of input voltages: 24‑56.7V DC for battery‑backed or DC distribution systems, and 24V, 48V, 120V, or 230V AC for direct connection to industrial AC mains. This universal input eliminates the need to stock separate modules for different power networks. For a machine builder shipping equipment to multiple countries with different mains voltages (e.g., 120V US, 230V Europe), a single module type covers all variants. The AC input uses a rectifier to produce DC internally; the DC input passes through directly.

        The 6ES7138-4CB11-0AB0 includes a user‑replaceable fast fuse (5x20 mm, 250V, 10 A) that protects the module and downstream I/O against short circuits and overloads. When the fuse blows, the green FSG (Fuse Status Good) LED turns off, immediately indicating the problem. A red SF (Group Error) LED also lights, providing a clear visual fault indication. The ability to replace the fuse without replacing the entire module reduces maintenance costs and downtime – a spare fuse can be stocked and swapped in minutes.

        The 6ES7138-4CB11-0AB0 is just 15 mm wide, making it one of the narrowest power modules available. In a control cabinet with limited space, this compact width allows more I/O modules to be placed in the same rack. The module weighs only 34 g, which is negligible for DIN rail mounting. However, the small size imposes thermal limits – the module must dissipate up to 5 W of heat, and the current carrying capacity is derated at higher ambient temperatures. For DC operation at 30°C, the module can supply 10 A; at 40°C, 9 A; at 60°C, only 7 A. For AC operation, the derating is even steeper: 8 A at 30°C, 7 A at 40°C, and 5 A at 60°C.

        • Potential Grouping: In an ET 200S station, this module is used to initiate a new potential group when independent power supply circuits are needed for different types of modules (e.g., separating sensor power supply from actuator power supply).
        • Load Power Monitoring: Widely used in scenarios requiring real-time voltage monitoring of external 24V DC power supplies. The module alerts the CPU upon voltage loss, suitable for critical processes such as automotive manufacturing, packaging lines, and water treatment.
        • Emergency Stop Control: By inserting a power module at a specific location, the power supply to a subsequent group of modules can be centrally shut off without affecting communication across the entire I/O station.
        • Industrial Safety Certifications: UL, cUL, and CE certified.
        • Electromagnetic Compatibility (EMC): Complies with EN 61000-6-2 (Industrial Immunity) and EN 61000-6-4 (Industrial Radiation Limits) standards.
        • Environmental Compliance: RoHS compliant; IP20 protection rating (requires installation in a cabinet).
        • Hazardous Location Classification: Approved for Class I, Division 2, Groups A, B, C, and D hazardous environments, and complies with ATEX explosion-proof standards.
        • Must be installed on a dedicated TM-P terminal block (such as 6ES7193-4CC20-0AA0 or 6ES7193-4CC30-0AA0).It terminates the left-side potential group and opens a new power distribution path on the backplane bus.
        • Module Interoperability:Supports all standard ET 200S electronic modules (digital, analog, and functional modules).Its diagnostic information (voltage loss) can be fed back to the S7-300, S7-400, or S7-1500 controller via the IM 151 series interface module.
        • Hot-swap (RIUP): Supports "hot-plugging," ensuring that module replacement does not interfere with backplane data communication, significantly improving system maintenance efficiency.
        Description
        The 6ES7138-4CB11-0AB0 is a power module for the SIMATIC ET 200S distributed I/O system. It supplies power to I/O modules and field devices. The module accepts a wide input range: 24‑56.7V DC or 24/48/120/230V AC. It provides overvoltage protection and has a replaceable fast fuse (5x20 mm, 10 A, 250V) for short‑circuit protection. 

        When using the 6ES7138-4CB11-0AB0, engineers can power up to 10 A at lower temperatures (derated at higher temperatures). For DC operation up to 30°C, maximum current is 10 A; at 60°C, it is 7 A. For AC operation up to 30°C, maximum current is 8 A; at 60°C, it is 5 A. 

        The 6ES7138-4CB11-0AB0 provides electrical isolation between the load voltage and the backplane bus (tested at 1500V AC). It also provides isolation between power modules. Current consumption from the backplane bus is max. 9.5 mA; from the load voltage (no load) it is max. 9 mA. Maximum power dissipation is 5 W. 

        For legacy ET 200S system expansions or repairs, the 6ES7138-4CB11-0AB0 is a versatile power module for mixed DC/AC supply networks. It requires external overcurrent protection for the supply lines as per local electrical codes. The fuse (order number: 6ES7193-4KA10-0AA0) is intended as supplementary protection only. 
        Alternative Names
        6ES7138-4CA50-0AB0 6ES7138-4CA00-0AB0 6ES7138-4CF00-0AB0 6ES7138-4CB11-OABO
        Technical notes
        The 6ES7138-4CB11-0AB0 provides electrical isolation between the load voltage and the backplane bus, tested at 1500V AC. This protects the ET 200S backplane and the higher‑level controller from voltage spikes originating on the field power supply.An external overcurrent protection device (circuit breaker or fuse) must be installed on the supply lines as required by local electrical regulations (IEC, NEC, etc.).
