GE PMC422-LAM D2 8-Port Serial Controller PMC Module

The GEPMC422-LAM D2 is an 8-port industrial serial controller module designed to integrate multiple asynchronous communication channels into a single compact PMC slot.

Each channel is supported by an independent 16C550-compatible UART, enabling stable and parallel communication with multiple field devices. The module supports RS-232, RS-422, and RS-485 standards, making it highly flexible for mixed industrial communication environments.

With programmable baud rates and high FIFO buffering, the PMC422-LAM D2 ensures efficient data handling even under high-load conditions. Its PCI 32-bit interface allows seamless integration into industrial computing systems, while DIP-switch and software configuration options provide deployment flexibility.

Engineered for harsh environments, this module is widely used in automation control systems, transportation platforms, energy infrastructure, and embedded industrial computing applications where stable multi-device serial communication is required.
