Configuring Mixed Voltage and 4-20mA Inputs - Wzzard Analog Input Node


Q: Customer wants to connect both voltage and milliamp sensors to a Wzzard Analog Node. 

A: The Analog Input Wzzard nodes have either 2 or 3 inputs that are configurable for either milliamps or Volts. (but not 1 of each). 

For applications that require a mix of Voltage and Milliamp inputs, you must configure the node for voltage input and supply an external 250Ω shunt resistor across the input that is to be configured for milliamps.
