Frequently Asked Questions (FAQ)

• What software do I need to configure this analog module?
  You need Rockwell Automation’s Studio 5000 or RSLogix 5000 programming software.
• Can I use different signal types on different channels simultaneously?
  Yes, each channel configures independently for various signal types.
• What is the minimum load impedance for voltage outputs?
  The voltage outputs require a minimum load impedance of 1kΩ for proper operation.
• Does this module support temperature sensor inputs directly?
  No, you need signal conditioners for thermocouples or RTD temperature sensors.
• What is the step response time for current inputs?
  The current inputs reach 63% of final value in approximately 18.2 milliseconds.
