and alarms. Only passive dry contact signals are supported. It is recommended that the
signal transmission distance not exceed 10m.
step 1
Strip the protection layer and insulation layer of the dry contact input 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 the plug "DI" outside Logger4000, as shown below.
Port "OV" and Port "1" are taken as an example.
