Functional Description
This product features a pair of intelligent 8-bit parallel digital I/O units that communicate with each
other without requiring a connection to a PC. When an input is turned on at one of the units, it will
cause the corresponding relay to switch on the other unit. As long as the input stays active, the
corresponding relay will remain energized on the other unit. If power is lost to either unit, the other
unit will retain the last valid commanded position for the relays. When power is restored to the
first unit, any changes that occurred to the eight inputs would then be communicated to the unit
that didn’t lose power, and the relays would follow the newly reported state.

Manual WWP-IIRO-8
The units are packaged in NEMA4 enclosures for remote installation in harsh environments.
These units act wirelessly, saving time and money associated with wired installations. The units
can work at various distances up to 7 miles with the standard antenna shipped with the product.
Alternate antennas may be used to boost signal strength.
The 8 isolated inputs can be driven by either AC or DC signals and are not polarity sensitive.
Input signals are rectified by photocoupler diodes. Standard 12/24 AC control transformer outputs
can be accepted as well as DC voltages. The input voltage range is 3 to 28 volts (rms). Unused
power dissipates through a 1.8KΩ resistor. External resistors connected in series with this may
be used to extend the input voltage range. Each input circuit contains a switchable slow/fast filter
that has a 4.7 ms time constant. (Without filtering, the response is 10 μs) The filter must be
selected for AC inputs in order to eliminate response to zero crossings, however, it is also
valuable for use with slow DC signals in a noisy environment. A filter is individually selected when
a jumper is installed onto any of the positions ‘FILTER 0' thru ‘FILTER 7'.
A built-in watchdog timer resets the unit if the microcontroller "hangs up".

Chapter 2: Installation
Prior to installing the pair into their final locations, it is recommended you bench test the units side
by side to become familiar with their response times, major features and I/O interfaces.
Gain access to the inside of the enclosure by removing the four lid screws, then set the lid and
these screws aside.
This is what you should see:

Power
If you ordered two of the optional accessory PWR-ACDC-12V along with the WWP-IIRO-8, they
ship pre-wired into the appropriate screw terminals.
If you didn’t order the optional power supply, you’ll need to provide a DC power source between
7.5V and 15V. Carefully pull up on the input removable screw terminal board to remove it. Route
your power supply wires through the gland on the right and make the connections referring to the
connector pin assignments in Chapter 5.

Manual WWP-IIRO-8
Antenna Installation
Screw the directional antenna onto the coaxial connector on the side of the enclosure until it is
snug. Screw the second antenna onto the second unit.
Test Setups
There are three scales of test setups from basic to thorough.
Bare Minimum Test
Simply apply power to both units and observe the red RX LED in each unit. If both RX LEDs are
blinking, the units are communicating with each other.
Medium Scale Test
This test should consist of a means to control (switch) power to each input independently, thereby
providing a means to switch each relay in the other unit. One way to perform this test would be to
have eight twisted pairs of wire at least 12 inches with each wire end stripped, then connect each
twisted pair to an input. Tighten each screw terminal down onto the stripped wire end until all
eight connections are completed, then route the twisted pair bundle through the gland. Re-install
the removable terminal block onto the input header. Apply power to both units, then apply a
voltage to each input pair one at a time and listen for the relays in the other unit to click, following
the input status of the first unit.
Thorough Scale Test
Using an I/O utility accessory with switches, screw terminals and LEDs such as the TAD8-16, you
could wire up the power supply return to the “B” side of each input, and the power supply positive
to one side of each switch. Connect the other side of each of the eight switches to the “A” side of
each input. Then wire the power supply return to the cathode of each of the eight LEDs and
connect the power supply positive to the common “C” terminal of each relay. As a final set of
connections for the first unit, connect the normally open “NO” contact terminal of each relay to the
anode of each LED on the accessory board.
On the second unit, wire up the terminal boards with the power supply positive at each relay
common and the power supply return to each “B” input. Then make a one-to-one connection
between each NO relay contact and each “A” input.
Power on both units and toggle each switch to perform a “round-trip” test. Each switch that gets
toggled into the first unit should control the corresponding relay in the second unit. When the
relay in the second unit switches, it will switch power to the input of the second unit, which will
then switch the corresponding relay in the first unit.
Verify Wireless Connection
Make sure that the green LED is illuminated and that the red LED is blinking in each unit.
The signal strength of the antenna can be affected by various things. If possible, mount the units
as high as possible within line of sight. If the signal passes from building to building, installing the
units near a window can help maintain signal strength. High gain antennas are also available
which can increase the gain up to 11dBi. Consult factory.

Input and Relay Connections
Route all input wiring through the same gland that you routed power. Route all output wiring
through the other gland. Make connections per the connector pin assignment table in Chapter 5.
Signal arrangements are intuitive on the removable terminal blocks.

Option Selections
Filter Response Jumpers
Jumpers are used to select input filtering on a channel-by-channel basis. When jumper FLT0 is
installed, additional filtering is introduced for input bit 0, FLT1 for bit 1, etc. This additional filtering
must be used when AC inputs are applied.

Temperature De-rating:
Based on the power applied, maximum operating temperature may have
to be de-rated because internal power regulators dissipate some heat.
For example, when 7.5VDC is applied, the temperature rise inside the enclosure is 7.3°C above the
ambient temperature.
Maximum operating temperature can be determined according to the following equation:
VI(TJ = 100) < 19.6 - TA/6.83
Where TA is the ambient temperature in °C. and VI(TJ = 100) is the voltage at which the integral voltage
regulator junction temperature will rise to a temperature of 100 °C.
(Note: The junction temperature is rated to 120 °C. maximum.)
For example, at an ambient temperature of 25 °C., the voltage VI can be up to 15.9V.
At an ambient temperature of 100°F (37.8°C), the voltage VI can be up to 14V.
