Limitless™ WDRR Series
The Limitless™ WDRR Series is supplied with one configurable NPN/PNP type "low battery" output intended to be
used with a customer provided PLC. The output changes state when one or more of the Limitless™ inputs has a
low battery. 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:
- Low battery output 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:
- Low battery output 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.
Lost RF Link output connection:
"Lost RF Link" output intended to be used with a customer provided PLC. The output changes state when one or
more of the Limitless™ inputs has lost RF Link with the WDRR. 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:
- Lost RF link output 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:
- Low battery output 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.
