Reliable RTD Measurement & Conversion

QD-6917 / QD-6918 / QD-6921 is a rtd input safety barrier designed around “Reliable Rtd Measurement & Conversion.” Provides dependable RTD measurement for industrial automation systems. The product is organized around this specific field requirement without adding unrelated functions to the measuring point. The feature is directly relevant to control cabinet, hazardous-area instrument loop and industrial process projects. Improve measurement clarity and maintenance efficiency in control cabinet applications, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation.

Flexible Multi-channel RTD Integration

QD-6917 / QD-6918 / QD-6921 is a rtd input safety barrier designed around “Flexible Multi-channel Rtd Integration.” Model options QD-6917, QD-6918, QD-6921 match different channel and point-count requirements. The channel and model arrangement makes it easier to match the number of field points without changing the overall cabinet architecture. The feature is directly relevant to control cabinet, hazardous-area instrument loop and industrial process projects. Handle more monitoring points with fewer separate cabinet modules, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation.

Intrinsically Safe RTD Isolation

QD-6917 / QD-6918 / QD-6921 is a rtd input safety barrier designed around “Intrinsically Safe Rtd Isolation.” Separates the hazardous-area RTD loop from the safe-side control system. The isolated signal path separates the hazardous-area device from the safe-side control system and helps limit unwanted electrical interaction across the barrier. The feature is directly relevant to control cabinet, hazardous-area instrument loop and industrial process projects. Protect hazardous-area loops while keeping safe-side data stable, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation.
