Introduction
The BinMaster WR-90 is a rugged, customizable, point-to-multipoint wireless bridge. It offers a
highly-flexible means of getting analog, digital, and Modbus® signals from where you have them
to where you need them. Modular input/output cards and expandable field units mean that the
WR-90 can be customized to meet the needs of any wireless application.
The WR-90 is simple to order, simple to configure, and easy to trust with your application. It can
be ordered as either preassembled kits or as individual, modular components. Guaranteed
ranges assure it will work with your application or you can send it back - no questions asked. A
wireless survey tool is available for those installations that require a site survey for longer
distances, making it easy to verify the setup will work the first time.
Field units accept analog, discrete, and Modbus® inputs and wirelessly broadcast them to the
WR-90 base station. The base station can recreate these signals with its onboard RS-485 or
analog and digital I/O cards. It can also be programmed to activate relays or output
analog/digital signals to the field units. Just put the field units wherever there are process
signals and the base station in the control room.
Fixed or remote antenna modules as well as a wide range of accessories are available,
including mounting kits, antenna-related accessories, and repeaters. The antenna may be
directly attached or remotely located. High gain directional antennas are also offered.

Pre-Installed Conduit Plug
The WR-90 field units are supplied with one pre-installed optional conduit plug for installations that do not
require the use of both conduit entries. The conduit plug includes an internal hexagonal socket recess for
removal.
Base Station Conduit Holes
No predrilled conduit holes are provided in the base station enclosure from the factory. Drilling of conduit
holes is left to the end user so that they may be placed wherever appropriate for the application. Be sure
to use suitable hardware (cable glands, plugs, etc.) in order to maintain NEMA 4X/IP66 rating on the
enclosure.
Mounting Instructions
The base station can be wall mounted using the included mounting hardware. Securely screw the four
brackets into the threaded holes provided at the rear of the enclosure with the bend facing toward the wall
in order to provide the necessary clearance. Then, secure exposed mounting holes to wall.
The field units have two mounting holes that may be used for a 1.5” pipe mounting or wall mounting.
Alternatively, the unit may be supported by the conduit using the conduit holes provided. The antenna is
threaded into one of the three conduit holes and may be moved as appropriate for the installation.
It can also be mounted by using the PDA6963-BM mounting bracket in order to orient the device antenna
away from the pipe. Refer to Mounting Dimensions on page 40 for details on space requirements.
Cover Jam Screw
The cover jam screw should be properly installed once the field units have been wired and tested in a
safe environment. The cover jam screw is intended to prevent the removal of the units’ cover while in
operation without the use of tools. Using a M2 hex wrench, turn the screw clockwise until the screw
contacts the unit. Turn the screw an additional 1/4 to 1/2 turn to secure the cover.
Caution: Excess torque may damage the threads and/or wrench.

Power Connector
Power connections are made to a two-terminal connector labeled
POWER in Figure 1.
Make sure that the power supply can provide 24 VDC to the
wireless base station.
Analog Input Connector
The analog input module can accept either 4-20 mA, 0-10 V, 0-5 V,
or 1-5 V. The appropriate input type must be independently
programmed for each input channel.
The analog input will not interfere with any existing HART signal on
a 4-20 mA current loop. However, the HART signal will not be
transmitted wirelessly.
Analog Output Connector
The mA output module can be programmed to output a 4-20mA
analog signal associated with a remote field unit’s analog input or
Modbus register.
The signal can be transmitted to any device scaled to read a 4-20
mA signal as shown at right. The analog output is internally powered;
no external power supply is required.
Digital I/O Connector
The digital input module includes four independently programmable
I/O channels. All digital connections are referenced to ground; digital
input connections have an internal pull-up resistor. Each connection
may be set as either an input or an output.
In the diagram to the right, D3 is a digital input and D4 is a digital
output.

Relays Connector
The relays module includes two mechanical relays. Relay connections
are made to the six-terminal connector shown to the right.
Each relay’s C terminal is common only to the normally open (NO) and
normally closed (NC) contacts of the corresponding relay.
If a field unit’s digital input channel is mapped to a relay module
channel on the base station, the effect may be opposite of what is
expected. An open connection at the digital input will result in the relay
going into an active state. This is because the digital input channels
are active low. This can be changed by swapping the NO and NC
connections to the relay channel.
Switching Inductive Loads
The use of suppressors (snubbers) is strongly recommended when switching inductive loads to prevent
disrupting the microprocessor’s operation. The suppressors also prolong the life of the relay contacts.
Suppression can be obtained with resistor-capacitor (RC) networks assembled by the user or purchased
as complete assemblies. Refer to the following circuits for RC network assembly and installation:
Figure 7. AC and DC Loads Protection
Choose R and C as follows:
R: 0.5 to 1 Ω for each volt across the contacts
C: 0.5 to 1 µF for each amp through closed contacts
Notes:
1. Use capacitors rated for 250 VAC.
2. RC networks may affect load release time of solenoid loads. Check to confirm proper operation.
3. Install the RC network at the device's relay screw terminals. An RC network may also be installed
across the load. Experiment for best results.
Figure 8. Low Voltage DC Loads Protection
RC Networks
RC networks should be applied to each relay contact switching an inductive load.
Note: Relays are de-rated to 1/14th HP (50 watts) with an inductive load.

Signal Connector
The analog input may be either 4-20 mA, 0-10 V, 0-5 V, or 1-5 V.
The appropriate input type must be programmed for each unit.
Once the appropriate input type has been programmed, wire the
analog signal source to the device as shown in the diagram at
right.
The analog input will not interfere with any existing HART signal
on a 4-20 mA current loop. However, the HART signal will not be
transmitted wirelessly.
4-20 mA Output Connector
The 4-20 mA output corresponds with the analog input signal on
the paired wireless device. The analog output signal is always
4-20 mA, regardless of the input type on the other wireless
module.
For instance, if the analog input type on the first device was
0-10 V and the input value was 5 V, the second device would
output 12 mA.
Connect the mA OUT terminals to a device scaled to read a
4-20 mA signal.
The analog output is internally powered; no external power
supply is required.
Digital I/O Connector
All digital connections are referenced to ground. The base
station I/O settings determine the I/O settings of the field units
(e.g. if D1 of the base station is an input then it can only be
mapped to a digital output of a field unit).
Note: Each connection may be set independently in the
device settings as either an input or an output. In the
diagram to the right, D4 & D3 are digital inputs and D2
is a digital output.

Setup and Programming
The base station and field units are factory calibrated
prior to shipment to read analog inputs in milliamps or
volts depending on the input selection. The calibration
equipment is certified to NIST standards.
Overview
There are no jumpers to set for wireless device input selection. Setup and programming of the base
station is done using WR Manager programming software. Setup of the wireless field units is done either
wirelessly through the base station using WR Manager programming software or via direct USB
programming with WR Manager. The field units’ programming buttons located underneath the enclosure
cover are for very limited programming options, such as network ID and Modbus address.
Programming the Base Station
The base station is programmed using WR Manager programming software. WR Manager can be found
on the included CD.
Once the software is running, power the unit using a 24 VDC power supply and connect the base
station’s micro USB port to a PC using the provided USB cable.
Note: Base station must be powered externally prior to programming via USB.
The PC will automatically install the appropriate device drivers. Once this has completed, the device will
appear in the Device list at the top of the WR Manager window. Click Connect.
