The local I/O is provided primarily for the analog output features. See Local I/O
operation section for details on configuring local analog inputs.
NOTICE: Digital outputs utilize 5-volt open collector logic with very low
current. LACO recommends using a solid-state relay with a 5-volt coil (P/N:
LMSA5981) to drive other voltages (i.e. 24 VDC) or larger current loads.
