AD Expantion Module

Add Analog to Digital Input to any UXP Port

Add Analog to Digital Conversion (A/D) to any NCD ProXR controller with a UXP Port (look for UXP in the part number) or any Analog to Digital Boards (Look for AD in the part number) using the UAD1216 Expansion Module! The UAD1216 is an 8-Bit/12-Bit 16-Channel Analog to Digital Converter Expansion Module designed to attach to any NCD ProXR controller with a UXP expansion port. That's right, turn your existing controller into an analog to digital converter! You cannot daisy chain different types of applications to the same controller however. In other words if you plug in an A/D Converter you will not be able to plug a Potentiometer or Contact Closure module. You will not be able to plug a A/D expansion into a Contact Closure or Potentiometer. For controllers that are equipped with a UXP Expansion port (and are suitable master devices for UXP Series Expansion) simply look for UXP in the part number. All Contact Closure Expansion Modules have an input and an output so you can simply daisy chain the boards together until you reach the number of contacts you are looking for up to a total of 256 including any A/D inputs there may be ob the master controller.

Ideal for Monitoring Voltages

While Analog to Digital Converters are ideal for monitoring voltages in the range of 0 to 5 volts DC. Our current product line is widely used for Temperature monitoring, Light Level monitoring, with minimal integration time. Analog to Digital conversion is the process of converting a voltage to a number. The higher the voltage (not exceeding 5VDC), the higher the number. 8-Bit Analog to Digital Converters offers numeric values from 0-255. 10-Bit ADC offers numeric values from 0 to 1023. 12-Bit A/D offers numeric values from 0-4093. Simply query the controller to ask it the voltage on the A/D input.
