The MCD Elektronik X-MUX32X4 V1.1 CrossBar Relay Board is a 32-by-4 relay crossbar matrix on a compact PCB, designed to route up to 32 input signals to four outputs through controlled relay contacts. Version 1.1 denotes the current revision of this CrossBar Multiplier board from MCD Elektronik. This relay-based interface card is suited for signal routing in test rigs, automation projects, or development setups where discrete, software-controlled line switching is required.
