• Installation in Enclosure
Programmable logic controllers are open-type devices that must be installed and
used within conductive control cabinets. Please use the programmable logic
controller while installed within a conductive shielded control cabinet. Please secure
the cabinet door to the control cabinet (for conduction). Installation within a control
cabinet greatly affects the safety of the system and aids in shielding noise from the
programmable logic controller.

• Differential-Line-Driver (AM26C31 or equivalent) and open collector output
encoders are available for the FX -2HC.

/ F X 3 U C
• The FX
-2HC has two outputs per channel. When the counter value coincides with
3U
an output compare value, the appropriate output is set ON. The output transistors
are individually isolated to allow either sink or source connection methods.
• Various counter modes, such as 1-phase or 2-phase, 16-bit or 32-bit modes, can be
selected using commands in the sequence program. Allow the FX
run only after setting these mode parameters.
