Power Supply Connections; Npn Or Pnp Output Connections - Honeywell Limitless WDRR Series Installation And Technical Manual

Limitless™ WDRR Receiver

6.3 Power Supply connections

Refer to Figure 2. The Limitless™ WDRR Series has two (2) cage clamp screw terminals on the housing's
bottom right. A regulated voltage supply of 10 Vdc to 28 Vdc needs to be connected to the power supply
terminals identified as "+"
NOTICE
The measured voltage across the output "-" terminal  and the output "+" terminal  is
nominally 1.5 Vdc less than the voltage supplied.

6.4 NPN or PNP output connections

Refer to Figure 2.
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.
