Schneider 110CPU41102 CPU Power Supply

The Schneider 110CPU41102 serves as an integrated CPU and power supply for Modicon M340 systems. This unit combines processing logic with power conversion in one module. You will find it in compact control cabinets where space is limited. It delivers 24 VDC to both the CPU and connected I/O modules. Therefore, this unit reduces panel space and simplifies wiring.

This unit measures 105 mm in height and 70 mm in width. Its depth reaches 85 mm for DIN rail mounting. The unit weighs approximately 0.52 kilograms. It contains one 32-bit processor and five electrolytic capacitors. Four status LEDs indicate CPU and power supply health. Additionally, you get one mini-USB programming port for configuration.

Internal Architecture and Energy Storage

The Schneider 110CPU41102 stores moderate energy in its input filter. Five electrolytic capacitors hold approximately 800 microfarads of total capacitance. This storage maintains operation during 10 ms supply interruptions. A 32-bit processor runs at 150 MHz for fast logic execution. The unit includes 4 MB of flash memory for user programs. Two separate DC-DC converters generate internal 5 V for logic. One converter also provides 24 VDC for sensor power loops. A built-in real-time clock maintains time during power cycles.

Connection Interfaces and Wiring Details

You will find a 10-pin removable terminal block on the bottom. This block accepts 24 VDC input plus field power connections. Connect the positive 24 VDC wire to the +24V terminal. Connect the negative wire to the 0V terminal. Use 16 AWG copper wire for all power connections. The Schneider 110CPU41102 includes a mini-USB port on the front panel. Use a standard USB cable to connect to a programming PC. Four LEDs show power presence, running status, errors, and I/O state. The module also provides a 24 VDC output for powering sensors.

Installation and Configuration Steps

You mount this unit onto standard 35 mm DIN rail. First, hook the top clip onto the rail edge securely. Then, press the bottom downward until it clicks into place. Connect the 24 VDC supply wires to the input terminals. The Schneider 110CPU41102 automatically powers up when you apply DC. Use EcoStruxure Machine Expert software to connect via USB. Download your program logic to the internal flash memory. The CPU supports up to 512 I/O points on expansion buses. Verify the green PWR and RUN LEDs before commissioning. Always use a regulated 24 VDC power supply for reliable operation.
