STACK 104 Family

Stackable mobile computer family based on PC104 modules

The STACK 104 is a modular system architecture that leverages the inherent stacking nature of PC/104 modules. The system can be expanded by adding more modules to the core that consists of a CPU head and power supply devices required in every system. The use of high density connectors makes the STACK 104 ideal for applications that require a high I/O density or high levels of isolation such as can be found on feeder driven trains or metros.

  • I/O intensive mobile computing
  • High voltage train systems
  • Insulated controllers
  • High availability systems
  • Video surveillance
  • Transportation applications

A STACK 104 system is based on modular PC/104 boards each installed in a purpose-built frame stacking together with flanged end plates.

High Resistance
A high resistance Zinc, Aluminium, Magnesium and Copper alloy (ZAMAC) is used that makes the system lightweight and durable in harsh and high vibration installations.

Variety of Configurations
A system consists of three subsections, the CPU head, a power supply and I/O boards. Various CPU and power supply sub-systems are available, each targeting different applications. A variety of I/O modules can be integrated into the expandable STACK 104 system to complete the functionality requirements.
