IS215UCVDH5A is a Double-Slot Controller Board developed by GE.

It is a part of Mark VI control system. The UCVD is a dual-slot board powered by a 300 MHz AMD K6 processor and equipped with 8 MB of flash memory and 16 MB of DRAM.

The UDH is connected via a single 10BaseT (RJ-45 connector) Ethernet port. It has eight status LEDs in a double column. When the component is operating normally, the LEDs are turned on in a rotating pattern.

When an error occurs, the LEDs flash an error code. There are dedicated GE ports.The module includes a control block language as well as analog and discrete blocks. Boolean logic is also represented in ladder diagram format.

This model features a 300 MHz AMD K6 processor, 16 MB of DRAM, and 8 MB of flash memory. The QNX operating system is used by this device. This operating system, like Unix, is a real-time operating system. It is primarily used in industrial applications that require high speed and reliability.

The UCVD has two columns of eight status LEDs. When the controller is turned on, these LEDs light up sequentially in a rotating pattern. When an error condition occurs, the LEDs flash an error code to identify the problem.
