Low battery output connections
Refer to Figure 2.
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
to PLC sourcing input
- Connect Output “+” terminal
to PLC common
- 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
to PLC sinking input
- Connect Output “-” terminal
to PLC common
- 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 connections
Refer to Figure 2.
The Limitless™ WDRR Series is supplied with one configurable NPN/PNP type “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
to PLC sourcing input
- Connect Output “+” terminal
to PLC common
- 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
to PLC sinking input
-Connect Output “-” terminal
to PLC common
- 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.
