Note that job Code 0 (0, 0, 0, 0) is not a valid job code and does not cause
a job recall operation. Ex: If the last job recalled was Job 10 and the inputs
are set to code 0, then Job 10 still dictates the active job settings.
The digital inputs (DI1, DI2, DI3, DI4) and the digital outputs (DO1, DO2, DO3,
DO4) are set for “Sourcing” as shipped from the factory. They can be
changed to “Sinking” by moving two optical isolator chips (U28/U44 for
inputs; U43/U42 for outputs) on the internal microprocessor controller if
desired. They are completely isolated and floating from the internal power
levels and they are not required to be set the same. The inputs and outputs
are set as a group so all 4 signals will be the same configuration. You may
set one for “Source” and the other for ”Sink” if required by the application
interface. This can eliminate relay logic conversions to save parts and panel
space for some PLC input/output cards. The chips are both optical isolator
chips (PS2501-4 quad optical isolators; digikey part# PS2501-4-ND, as of
this printing) available from most electronic distributors. The isolators are
rated for 30 VDC, 100 ma max – do not connect AC voltage levels!
