Extend the Signal Range of PDW30 and PDW90 Wireless Systems with PDWR Wireless Signal Repeaters

PDWR wireless signal repeaters are used to improve the connectivity in PDW30 point to point and PDW90 point to multi-point wireless systems. They will generally increase signal range of the system by another 1 mile line-of-sight or 500 feet indoor.

The repeaters are simple to install as they only require power and a network ID. Any PDW wireless units in range of the repeater with the same network ID will retransmit through it, thus increasing signal strength.

PDWR repeaters can be used to broadcast over very long distances or around permanent obstacles.

The PDWR repeaters are available in either aluminum or stainless steel NEMA 4X, IP68 enclosures and these enclosures contain plenty of room for field wiring connections.

Key Features

PDW Manager Software

PDW Manager PC Programming Software

PDW Manager PC Software allows for programming the PDWR repeater units from a PC with a USB connection. The units connect to a PC via the USB connection on the side of the display module behind the cover of the enclosure.

Use of PDW Manager is required for programming advanced settings such as wireless encryption. PDW Manager is available for download at www.predig.com/pdwmanager.

CapTouch Through-Glass Buttons

CapTouch Through-Glass Buttons

The PDWR repeater units are equipped with four capacitive sensors that operate as through-glass buttons so that they can be operated without removing the cover (and exposing the electronics) in an unclean area.

CapTouch buttons allow the Network ID to be pro-grammed without removing the cover.

CapTouch buttons are designed to work under any lighting condition and are not affected by random changes in light or shadows. To protect against false triggering a long button press of about 2 seconds is required to wake up the buttons when they have not been in use.

Easy-To-Install Display Module

Easy-To-Install Display Module

The display module designed specifically for the PDWR wireless units are easy to remove making it convenient for wiring the unit. The display module is completely enclosed for added protection when wiring and handling.

Repeater Units Available in Aluminum or Stainless Steel

Repeater Units Available in Aluminum or Stainless Steel

The PDWR repeater units are available in an IP68, NEMA 4X aluminum or stainless steel enclosure. The enclosures feature a built-in flange for wall or pipe mounting, built-in loop for a stainless steel tag, locking screw, and hole for a tamper-proof wire & seal. The enclosure also includes two 3/4" threaded conduit openings for wiring. The PDWR repeater units can operate in temperatures of -55 to 75°C (-67 to 167°F).

Application Example

Extending Signal Range with PDWR Repeaters

The PDWR repeaters are used to retransmit wireless signals when connectivity between the PDW30 primary and secondary units or the PDW90 base station and field units are out of range or are obstructed by other objects or structures.

Power Connections

Power connections are made to a two-terminal connector labeled POWER. The PDWR is reverse polarity protected; it will not be damaged if wired backward.

Make sure that the power supply can provide between 9 and 30 VDC to the wireless device.
