Basic Models
These models provide a
present value LED and
front-panel control keys. Can
be connected to any Output
Board, or can be used for
display only without an
Output Board.
Set Value LED Models
These models provide a
present value LED, set
value LED, and front-panel
control keys. Can be
connected to Relay,
Transistor, or Combination
Output Boards.
