Industrial PC263 Relay Board

Industrial PC263 Relay Board (Amplicon PC263/PCI263 family) is a 16-channel reed-relay output board designed for PC-based control and automation. Each of the 16 digital outputs drives a reed-relay, with relay contacts closing when the corresponding output bit is set to 1, and the board's output states are readable back to confirm the current switch conditions. Available in ISA (PC263) and PCI (PCI263) variants, the boards expose a configurable I/O address (ISA base address) or PCI bus/slot address for integration into standard desktop or embedded systems. This relay board is commonly used to switch external circuits in automation, instrumentation, test rigs, and process-control setups where isolated, electromechanical switching is required. The PC263 family is supported under Linux via the Comedi driver amplc_pc263, reflecting its established role in software-controlled I/O expansion and hardware interfacing.
