8.1 Analog Inputs
A combination of loop powered (2-wire) and self powered (3 or 4-wire) analog input transmitters can
be used on the one module (AI-1, AI-10, IO-3 or IO-4).
By default, each analog input is designed to accept 4 to 20 mA. Removing a link on the back of the
module will allow 0 to 20mA operation for all channels of an AI-1, AO-2, IO-3 or IO-4. The current or
voltage range for all channels of an AI-10 module is software configurable.
