The PDA8068 USB serial adapter is used to connect the PD6830, PD6830X, and PD6730 directly to a computer via USB. This module connects the internal electronics module directly to a computer, and only allows for programming of the units. No live monitoring is possible with this module. This is ideal for quickly connecting to MeterView EX or ScanView EX for programming. USB and meter to adapter cables are included.
The Precision Digital PDW30 provides a simple, straightforward way to get an analog, discrete (digital) or Modbus signal from where you have it to where you need it – without having to run wires! It’s a point-to-point wireless bridge that is virtually plug and play right out of the box.
The PDW30 consists of a primary and a secondary unit and communication between the two is by-directional. That means you can send 4-20 mA, discrete and Modbus signals from the primary unit to the secondary unit and also send completely different 4-20 mA, discrete and Modbus signals from the secondary unit to the primary unit. For instance, the primary unit could send a 4-20 mA signal to the secondary unit corresponding to the level in a tank and the secondary unit could send a 4-20 mA signal to the primary unit to control a valve.
Primary and secondary 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, both units can be equipped with an optional, field installable, two relay module. These relays are rated Form A (SPST) 5A.
The specified range between the primary and secondary unit 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. And if the PDW30 system does not work in your application, you can return it for full credit!
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. And if the PDW90 system does not work in your application, you can return it for full credit!
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.
The PDWA3900 Yagi antennas are made to work with point-to-point and point to multi-point applications.
These high gain antennas are ideal to use with Precision Digital's PDW series because they give you the flexibility of installing the antenna exactly where you need to bridge your point-to-point or point to multi-point wireless process signals while keeping the PDW unit in a convenient location for monitoring.
Each Yagi antenna is factory tuned on a network analyzer for best power match and lowest VSWR, offering the best possible performance.
The PDWA3900 also comes complete with a mounting kit that includes stainless steel hardware.
Extension cable accessories are available to extend the distance between the Yagi antenna and the PDW30 or PDW90 wireless units. See Ordering Information for details.
