Expansion Board 16-Channel 5-Amp DPDT
XR165DPDT$336.00
XR Expansion Board
The XR165DPDT Expansion adds 16 5-Amp DPDT relays to a ProXR Board. This relay expansion board is designed to plug into the ProXR series relay boards, and includes the required XR Relay Expansion Controller cable. On-Board status LEDs indicate the on/off status of each relay. This expansion board operates on 12 Volts DC, and may be powered by connecting two-wires to the on-board screw terminal connector, or by plugging in power supply (sold separately) with a 2.1mm center positive barrel connector.

ProXR Expansion Board
This Expansion Board plugs into the XR Expansion Port on any ProXR Board to add more relays. Expansion boards can be daisy chained together to add the relays needed.
Add Relays as Your Needs Grow
The expansion board is compatible with the ProXR and Taralist Time Activated Relay boards. The ProXR and Taralist boards are fitted with an XR Expansion Port where you can add expansion boards. Expansion boards can be added until you reach 256 total relays. As you continue to chain expansion boards onto an XR expansion port, the total number of available relay banks will increase. Add expansion boards as needed in the future, whenever you require more relays simply order another expansion board.Linking XR Expansion Boards Together
XR Expansion Boards consist of a XR Input and XR Output Connector. Simply connect the XR Output of your ProXR Board to the XR Input located on the relay expansion board. Chaining more relays is easy. Simply connect the XR Output of your ProXR expansion board to the XR Input of your next expansion board. Mix and Match different relay types as your application requires. A 6″ expansion cable is included with this expansion board.Will Not Operate Independently
This Expansion Board gets it's commands from the main ProXR or Taralist board and will not operate independently. This board MUST be plugged into a ProXR or Taralist board to operate and will not function on it's own.Essential Power Requirements
This and all expansion boards require 12 VDC to operate. We offer a wall-wart type power supply at checkout if you need to plug this into a 110 wall outlet. Applying Good clean power to the board is essential for the operation of the board. Without good steady clean power from a regulated power supply the board simply will not function correctly. The PWR12 US power supply is a 120VAC to 12VDC 1.25A 60Hz regulated power supply and it plugs into the barrel connector on the board. The output connector is a 2.1mm I.D. x 5.5mm O.D. x 9.5mm Female R/A barrel connector. We also carry an international power supply with interchangeable adapters for international customers.

Maximum Relay Rating Notes
ProXR is capable of expanding to an absolute maximum of 256 Relays. In some cases, it may not be possible to control all 256 relays, particularly in applications where high noise levels may be involved. Experimentation may be required, as it is not possible for us to guarantee all users will be able to utilize all 256 relays in every application. Noise tends to accumulate when several expansions are connected together. For best results, the XR expansion cables must be as short as possible.DPDT Relays Installed
This board has DPDT relays installed. A single DPDT relay is made up of 2 SPDT switches. Each relay acts as two switches that are activated at the same time. This allows two independent signals to be switched at one time. In effect, there are two independent switches on a single DPDT relay - they will always switch together.
There are two connectors with Normally Open, Normally Closed and Common for each relay allowing two separate connections. The picture above shows the 4-channel connectors. The diagram to the right shows the how the arms of the common connector swing from the Normally Closed to the Normally Open positions when energized. Wiring to either the NO or NC can produce your desired results. Mix & Match
Expansion boards do not need to be the same relay amperage as the main board or other expansion boards. Mix & match expansion board to get the exact amperage for your switching needs.2-Million Cycles
ProXR series controllers are designed for long life, you should expect to get years of service from your controller and literally 2-million cycles from the relays on board. With a 5-year warranty and a money back guarantee you have nothing to loose! Place your order now, while everything is in front of you.This Board is RoHS Compliant

Power Supply Available
The PWR12 is regulated power supply providing clean power necessary for
the performance of these boards. The PWR12 US power supply is a 120VAC to 12VDC 1.25A 60Hz regulated
power supply and it plugs into the barrel connector on the board. The output connector is a 2.1mm I.D. x 5.5mm
O.D. x 9.5mm R/A barrel connector.

Induction Suppression
Controlling
an inductive load using our relay controllers requires the use of induction suppression capacitors. The purpose of this capacitor
is to absorb the high voltages generated by inductive loads, blocking them from the contacts of the relay. Without this capacitor,
the lifespan of the relay will be greatly reduced. Induction can be so severe that it electrically interferes with the microprocessor
logic of our controllers, causing relay banks to shut themselves down unexpectedly.
