Universal controller  controls of all Array Solution's Antenna switches

There are several jumpers on the main board:

1. Output level jumpers – Output level is determined by jumper located on board near the relays upper right corner of the board. The default position (positive) is appropriate for all Array Solutions products internal power source. Many users will want to use the EXT (external voltage source) jumper position to allow them to provide an external voltage source to the DB15 connector on the back. This will provide isolation between controller and the relay box outside as well as allowing the user to run higher voltage to the outside world to compensate for very long cable runs. Remember to connect the device being driven’s ground return to Pin 15 of the DB15 or directly to the negative side of the external power supply.

The Default position is INT (relay box will be powered from controller). If you move both jumpers to position EXT, controller will be galvanic separated from relay box (for maximal immunity). Don't forget attach external power into DB15 (see chart below). If you move only top jumper (near the connector DB15) to EXT position, unit will share GND, but relay box will be still driven by external positive voltage. (For example if you need more than 24V driving power). You will need to place the external power supply ground to the internal ground pin 13 or 15 in this mode.

2. Relay box personality jumpers -Three jumpers located on bottom right position determine controlled relay box. All open is Stack Master, etc. You must reset unit (OFF-ON) if you change these jumpers. The Array Solutions products described below give the settings for these jumpers.

 

You can power unit from 13.8V to 24V. Output voltage to relay box will be approximately 1V less than the input voltage when using internal power to drive them. You need not connect external power if you want power relay box higher than 13.8 V. Do not exceed 24V DC or you will blow the regulators on board.

150mA is minimal consumption without any relay switched on. Maximal consumption without relay box is 330mA (7 relays on for StackMaster).

Maximal relay box current should not exceed 700mA when using internal power for output drive

Using external power supply for output drive should not exceed 500 ma per relay being driven.

This you will never do with Array Solutions products all relays are either 40, 100, or 120 ma depending on the product.
