Table of Contents Chapter 1: Introduction ...........................................................................................................................5 Features ...................................................................................................................................................5 Applications............................................................................................................................................5 Functional Description ..........
Chapter 1: Introduction Features • Wireless Digital Input / Relay Output Module Pair • Each input on one unit is mapped to control the corresponding relay automatically in the other • 7-mile line of site communications over integrated non-licensed FCC radio modems • Removable omni-directional antenna without requiring access to inside of enclosure • 900 MHz unlicensed radio modem with frequency hopping spread spectrum technology • NEMA4 enclosure for harsh atmospheric or marine environments • T
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.

Ordering Guide WWP-IIRO-8 WWP-II-8/RO-8 Pair of WWM-IIRO-8's (8 Inputs / 8 Relays, x2) One WWM-II-8 paired with one WWM-RO-8 (8 Inputs / 8 Relays) Model Options -OEM Boards only (no enclosure) -HG High gain antenna – -24 2.4GHz wireless module Included with your board The following components are included with your shipment, depending on options ordered. Please take the time now to ensure that no items are damaged or missing.
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.
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.
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.
Chapter 3: Hardware Details 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.
