When using these relay controllers with Dampers or Sprinklers, you may need an independent 24VAC power source. We stock several versions. Click herefor a selection.

• Each of the 8 independent relays is equipped with a form C contact that is brought out to two plug in, detachable terminal strips.
• 1A @24VDC resistive
• 1A @120VAC resistive
• Relay contacts are designed for low current applications as well as power switching.
• Instruction Manual(PDF)

For those X10 control applications demanding isolated, dry contacts, we offer the latest addition to our product family, the Relay8.

The Relay8 is an 8-relay module that responds to X10 ON, OFF, ALL OFF and status request commands.

The Relay8 supports devices capable of sending a Status Request command. In addition to giving you the power to poll individual relays to determine their on/off status, it also allows your computer send a command to the module then check to see if the command was carried out. If not, the computer can automatically send the command again.

• Voltage 24 - 27v AC, 50 or 60 hz
• 120v AC to 24v, 300 ma, class 2, wall mounted transformer included
• Controller Current 30 ma
• Sprinkler Valve Voltage & Current 24v AC , 250 ma max (with supplied transformer)
• Two piece design allows user to unplug controller from sprinkler valve and power wiring.
• PC (RS-232 serial port) Used only to configure controller. Controller derives its power from PC. DB9
• Connects to X10's Tw523 or PSC05.
• Controller Size 3.8" x 2.4" x 1.0"
• Weight 4 oz
• Environmental 20 - 125 degrees
• Indoor or outdoor (if mounted in a weatherproof enclosure).

A complete irrigation schedule can be triggered by the reception of a single X10 power line carrier command. With its dual mode capability, each individual zone can be controlled independently if the user prefers.

Using a PC and our software all aspects of irrigation may be controlled over the Internet.

To configure the Rain8 you connect it to your computer (Windows or Mac) and run the configuration utility application. This allows you to define the X10 address zone assignments and set the operational mode. For maximum flexibility, once programmed you can run the Rain8 in two different operational modes:

The Rain8 can be used with nothing more than X10's Mini Timer. Anything that can generate a X10 command can trigger a complete irrigation sequence, cycling through all eight zones. When one zone times out, the next one starts. In this instance the time settings for each zone are stored internally. The Rain8 provides for two independent schedules, each with its own X10 trigger assignment and run times. More info...

A home automation program may generate X10 power line carrier signals to start and stop each zone. The actual timing controls, in this mode, are located in this PC program. This provides an easy means of adjusting run times for seasonal irrigation changes. As a safeguard, the user can set the maximum "valve on" time for each zone anywhere from 1 to 240 minutes. This guarantees that the sprinkler valve will turn off even in the absence of an X10 OFF command. As each sprinkler valve has its own default setting, this guarantees a minimum of wasted water in the advent of a lost X10 signal. Another safeguard to help in the conservation of water is the inter lock feature. Only one sprinkler valve is allowed on at a time.

NEW!

With the 2-way version (WG-RAIN8II below), you can determine which irrigation zones are on and which are off. Designed for use with X10-compatible computer interfaces and other devices that can generate the X10 Status Request command. In addition to giving you the power to poll irrigation zones to determine their on/off status, it also allows your computer send a command to the module then check to see if the command was carried out. If not, the computer can automatically send the command again.

Other differences between the two-way and the one-way Rain8:

• There are no limitations on the number of zones that may be active at one time.
• Default run timers can be disabled if desired.
• Responds the X10 "All Units Off" command.
• Manual mode only, does not have the auto mode capability of the one-way Rain8.

• Turn on or off each of the zone individually
• Turn off all zones on a specific module
• Turn off all zones on all modules
• Get the current status of all zones
• Default run timer for each zone to prevent over watering
• Up to 1000' between Rain8 and computer
• Installation Manual(PDF)
• Brochure(PDF)

Additional modules may be daisy chained to provide control and 24 VAC power to as many as 2040 irrigation zones from a single COM or USB port.

There is a single RS232 connection between the controlling computer and the "master" Rain8. The distance between the computer and the controller is up to 1000' and requires only 3 wires: TX, RX and GND.

The 24VAC power and network communications are transferred from master to slave-to-slave etc.

The network connection for the slave units is an 8 conductor RJ45. Each slave has a pair of these modular jacks to pass on data and power to the next one in a daisy chain. Each slave also has a RS232 connection that is used only to assign the address during the initial configuration.
