Brown wire connects to positive power supply terminal. Blue wire connects to negative power supply terminal.
NPN or PNP output connections:
NPN/PNP type outputs intended to be used with a customer provided PLC. A specific output will change when one
or more of the Limitless™ input(s) changes. The customer has the option of connecting the outputs for use as:
NPN- type current sinking or totem pole (current sinking); PNP-type current sourcing or totem pole (current
sourcing). See Section 1.3 for proper settings of the DIP switches. The connections to the customer's PLC would
be as follows for each:
NPN-type: Current Sinking or Totem Pole (current sinking) output connecting to a PLC sourcing input
- Connect NPN-type terminal
- Connect Output "+" terminal
- No connection to Output "-" terminal
PNP-type: Current Sourcing or Totem Pole (current sourcing) output connecting to a PLC sinking input
- Connect PNP-type terminal
- Connect Output "-" terminal
- No connection to Output "+" terminal
CAUTION
Do not apply direct power (supply voltage "+" or "-") to the "-" terminal  or "+" terminal  or any
of the NPN/PNP type output terminals as damage could occur to the WDRR electronics.
