Installing the 1756-HYD02 Module Chapter 2
Connecting LDTs to Your Hydraulic Module
Because the number of LDTs that you can connect to your 1756-HYD02
module is continually changing, we cannot list all the available LDTs here.
Figure shows the connections for two example LDT types–Temposonic and
Balluff–that were available for connection to the 1756-HYD02 module at the
time of this printing.
Table lists the LDT connections.
IMPORTANT
Remember, there are other suppliers with compatible LDTs.
Before connecting an LDT to your module, we recommend you
make sure it is the best available LDT for your application.
Also, when wiring an LDT to your module, always follow the
LDT manufacturer’s instructions on making connections.
