open contact, and NC/COM is the normally closed contact. It is recommended that the
signal transmission distance not exceed 10m.
step 1
Strip the protection layer and insulation layer of the dry contact output signal cable with
a wire striper, as shown in the figure below.
step 2
Assemble proper cord end terminals to signal cable whose protective layer and
insulation layer are stripped off and crimp them with a crimping tool.
step 3
Connect the cord end terminals to plugs "DO1"~"DO4" outside Logger4000, as shown
below. NO contact of Port "DO1" is taken as an example.
