Need help selecting CLICK PLC components? Use our configuration tool to configure and order.
PLC discrete AC I/O modules allow monitoring and control of ON/OFF signals and devices that operate with AC voltages up to 240 VAC, such as power relays, pumps and motor starters. Relay modules provide NO/NC contacts that switch user-supplied power on and off internally, allowing for higher current loads. Several CLICK AC I/O and relay modules are available.
AC I/O and relay output modules are now available for the CLICK
PLC control system. Up to 8 I/O modules can be connected to a CLICK
CPU module to expand the system I/O count to better meet the needs
of a specific process control application.
A powered CLICK CPU stand alone base unit can be used as
a complete PLC control system with eight input points and six
output points built-in
Or, the logic controller can be expanded with the
addition of up to eight I/O modules
A variety of I/O modules are available for flexible and
optimal system configuration />
The I/O numbering system is decimal rather than
The CLICK PLC system does not require a mounting base,
which saves on space
The CLICK CPU and I/O modules are connected together via
an expansion port on the sides of the modules
