Introduction to the CLICK PLC Mechanical Design
CLICK PLC Units
All CLICK PLCs are similar in appearance. Please see the diagrams below to familiarize
yourself with the PLC features. The main components located on the front of the PLC are
a removable 20-pin I/O connector, Run/Stop switch, communications ports and LED status
indicators. A removable 4-pin 24VDC input power connector is located on the bottom of
the PLC. The I/O module extension port is located on the right side of the PLC case. See
Mounting Guidelines in this chapter for module dimensions and Chapter 2 for CLICK PLC
speciο¬cations.
