Giddings & Lewis PiC900 502-03605-00 24V DC input module converts DC signals from 32 or 16 devices into logic levels that the CPU can use. Each signal is converted into a corresponding logic 1 or 0 which is transmitted through the system bus to the CPU module. An "on" signal is nominally 24 V DC, but can be any level between 14 and 30 volts. An "off" signal is any level below 5V. The wiring configurations may be sink or source.
