Wiring the Different Module Connectors
There are two types of module connectors for the Do-more I/O. Some modules have normal
screw terminal connectors. Other modules have connectors with recessed screws. The recessed
screws help minimize the risk of someone accidentally touching active wiring.
Both types of connectors can be easily removed. If you examine the connectors closely, you’ll
notice there are squeeze tabs on the top and bottom. To remove the terminal block, press the
squeeze tabs and pull the terminal block away from the module.
We also have DIN rail mounted terminal blocks, DINnectors (refer to our catalog for a complete
listing of all available products).

Link systems come with special pre–assembled cables with
the I/O connectors installed and wired.
WARNING: For some modules, field device power may still be present on the terminal block even though
the PLC system is turned off. To minimize the risk of electrical shock, check all field device power before
you remove the connector.
