EPC 50 3183045486 I O Motherboard for Industrial Embedded Systems

Product Overview

The EPC 50 3183045486 is an I/O motherboard designed for use in embedded industrial computers and automation controllers. This board serves as the backbone of the EPC 50 series system, providing connections for CPU modules, memory, power supplies, and I/O expansion cards. The motherboard is built to operate reliably in industrial environments with extended temperature ranges, shock and vibration resistance. It is typically used in factory automation, process control, and machine monitoring applications where a compact, fanless PC is required. The 3183045486 motherboard offers a variety of standard interfaces including PCI Express slots, USB ports, Ethernet, serial RS-232/485, and digital I/O headers.

Key Features of EPC 50 3183045486

The motherboard supports Intel or AMD embedded processors via a module interface, providing a scalable platform for different performance levels. It includes up to 16 GB of DDR3 or DDR4 SO-DIMM memory. The board features multiple PCIe Mini Card slots for adding Wi-Fi, cellular, or fieldbus modules. Storage options include SATA for 2.5" SSDs/HDDs and mSATA or M.2 for solid-state drives. The EPC 50 motherboard has wide voltage input (9-36 V DC) with overvoltage and reverse polarity protection, making it suitable for mobile or DC-powered installations.

The board provides isolated digital I/O lines (typically 8 in, 8 out) that can directly interface with industrial sensors and actuators without additional opto-isolation modules. It includes two to four Gigabit Ethernet ports, supporting teaming and redundancy protocols for real-time automation networks. The motherboard is compliant with industrial certifications (CE, FCC, UL) and is designed for 24/7 continuous operation.

Functional Description

The EPC 50 motherboard routes power and data between the CPU module, memory, storage, and I/O interfaces. The BIOS provides extensive configuration options for legacy COM ports, watchdog timer, and power-on after power failure. The isolated digital I/O can be programmed via the operating system (Windows, Linux) using standard APIs, enabling direct control of relays or reading of switch states. The board's wide-voltage input allows it to be powered from industrial 24 V DC supplies, and the built-in protection prevents damage from voltage spikes. The multiple Ethernet ports support real-time protocols such as EtherCAT, PROFINET, or Modbus TCP when used with appropriate software stacks.

Applications

The EPC 50 motherboard is used as the core of industrial panel PCs, embedded controllers for machine vision, data gateways for IIoT, and control platforms for automated test equipment. It can replace aging motherboards in existing EPC 50 systems or serve as a building block for custom automation computers.
