In its most basic form, the PDW90 consists of field units (up to 32) that accept 4-20 mA signals and transmits them wirelessly to a base station. The primary advantage of this system is how simple and economical it is to get multiple signals (not just 4-20 mA, also discrete (digital) and Modbus) from where you have them to where you need them – all without having to run wires!

The wireless communication between the field units and the base station is bi-directional. That means you can send 4-20 mA, discrete and Modbus signals from the field units to the base station and also send completely different 4-20 mA, discrete and Modbus signals from the base station to the field units. For instance, the field unit could send a 4-20 mA signal to the base station corresponding to the level in a tank and the base station could send a 4-20 mA sig-nal to the field unit to control a valve.

Field units are also equipped with four digital I/O that can each be independently programmed as an input or an output. A Loss of Signal warning is also available by connecting devices to the G and LS screw terminals.

To indicate alarm situations in the field, the field unit can be equipped with an optional, field installable, two relays module. These relays are rated Form A (SPST) 5A and are controlled by the digital outputs on the base station.

The base stations are available in configurations for 2, 6, or 16 I/O slots for a variety of field installable I/O modules. The available I/O modules are:

Dual Analog Input

Dual Analog Output

Dual Relay Output

Four Digital I/O

The specified range between the base station and field units is 1 mile line-of-sight outdoor and 500 feet indoor and repeaters are available to extend the range. A low-cost wireless survey tool, Model PDA10, is available to test the signal strength of your application before you buy.
