Ordering Information

To order output and communication boards, refer to the separate K31 data sheet called Output and Communication Boards . See page 155.
3 BASE UNITS
Model
Basic model
Present value LED and front-panel control
keys. Can connect to any output board or,
without an output board, can be used for
display only.
Set value LED model
Present value LED, set value LED, and
front-panel control keys. Can connect to
relay contact, transistor, or combination
output boards.
Note: "Set Value LED" models must be used with an output board in order for them to operate.
