the Analog Current/Voltage Combination Input/Output module provides up to 4 differential input current or voltage channels and 2 single-ended output channels with either current loop outputs or voltage outputs. Each channel can be ndividually configured for the current or voltage range, as applicable, required for your application. All module configuration is done through software, except for a jumper required for selecting the current input mode. All ranges can be configured using either the Logicmaster 90-30/20/Micro programming software configurator function or the Series 90-30 Hand-Held Programmer.
