Frequently Asked Questions

• What is sourcing vs sinking input configuration?
  Sourcing inputs provide voltage to the field device, while sinking inputs receive voltage from the field device.
• What types of devices work with this module?
  It works with proximity sensors, limit switches, push buttons, and other DC devices that don’t provide their own voltage.
• Can I mix different voltage signals on the same module?
  No, all inputs must operate within the 10-30V DC range and share a common connection.
• How fast can this module detect input changes?
  It can detect changes in as little as 0.3ms, making it suitable for high-speed applications.
• What is the purpose of the optical isolation?
  Optical isolation protects the controller from electrical noise and voltage spikes in the field wiring.
