Auxiliary I/O Retransmit Scaling


Welcome. This video will demonstrate auxiliary I/O retransmit scaling.

Before we begin, we will need to install the Control Panel software, which is provided free with your controller. Connect power to the controller and connect to your computer with a USB cable. 

First, connect to the controller using the USB interface.

The auxiliary I/O card is an optional component on our FUSION and Compact FUSION controllers. The card is located on the controller here. If your controller has an auxiliary I/O card, relevant options will be available to you on the control panel software.

You will see a -1000 in its model number, and this tab, the Aux I/O tab, will be part of your control panel.

The card has 2 digital inputs, digital 2 outputs, and 2 analog retransmits. You can see their statuses here on the control panel screen.

When we click on the Aux I/O tab, we can see Meter 1 and Meter 2 at the bottom of the screen. By default, both are set to 0 - 5 V DC. The Meter 1 Signal is set to RMS Load Voltage A, and the signal for Meter 2 is set to RMS Load Current A.

Let's do a couple of scenarios with retransmit scaling.

SCENARIO 1: Output = power 4-20 mA = 0 - 100%

You can choose up to two signals from the drop-down menus to retransmit. For our demonstration, let's change our output type to current, have Meter 1 output Power, and use 4-20 mA as 0 - 100 percent of full scale power.

We can check the Zone 1 tab for information about our fullscale settings. Here we see that fullscale power is equal to 9.6 killowatts.

Let's look at one more scenario. You may want to use a Direct Out test for trouble shooting or system start up. We change meter 2's signal to direct out. Let's also change the output type on meter 2 to 4 - 20 mA current.

Now we can enter a mA value in the Meter 2 Direct Out field, and the controller will output at that value.
