FAQ

  • What does "sinking input" mean?
    The module provides the path to ground (-). The field device must supply the positive voltage (+V) to the input point to activate it.
  • What is thermal derating?
    As temperature increases, the module can safely power fewer inputs simultaneously. For example, at 60°C, all 16 points can be on only at 125V DC.
  • Can it be used with 24V DC sensors?No, the minimum ON voltage is 74V DC. This module is specifically for high-voltage DC circuits, typically 125V DC.
