Frequently Asked Questions

• What is the difference between sourcing and sinking inputs?
  Sourcing inputs provide voltage to field devices, while sinking inputs receive voltage from field devices.
• How many modules can I install in one chassis?
  The number depends on your processor’s I/O capacity and the number of available slots in your chassis.
• What types of sensors work with this module?
  It works with proximity sensors, push buttons, limit switches, and other DC devices using sourcing configuration.
• Can I use this module in harsh environments?
  Yes, it operates in industrial environments with 5-95% humidity and temperatures from 0-60°C.
• What does the 8ms response time mean?
  The module takes up to 8 milliseconds to detect and report an input state change to the processor.
