8030-HOM-251. The Symax Class 8030 Type HOM-251. The input/output system consists of I/O modules and I/O racks. I/O modules are signal converters that translate the 5 volt DC signals used by the processor into the generally higher AC or DC voltages of the field I/O devices, and vice versa, I/O rack assemblies provide mounting slots and power connections for I/O modules, the processor, and other modules. Some racks have terminal blocks to which I/O devices are wired.
