QLCDM024DCBAN

The QLCDM024DCBAN is a Critical Discrete I/O Module designed for use within the APACS+ and QUADLOG safety-rated distributed control system platforms. Originally produced by Siemens Moore Products, this module plays a vital role in safety-instrumented system architectures, handling critical discrete input and output signals in demanding process control environments such as oil and gas, petrochemical, power generation, and other industries where functional safety is paramount.QLCDM024DCBAN

This particular unit is offered in used and fully tested condition, having undergone functional verification to confirm it performs to its original design parameters. The module operates on a 24 VDC supply and is engineered for reliable discrete signal processing, with current-sinking inputs and current-sourcing outputs ensuring broad compatibility with standard field devices and sensors. With a ROM version of 3.04, this module reflects a mature, field-proven firmware revision that has been deployed across countless industrial installations worldwide.QLCDM024DCBAN

Sourcing a verified pre-owned QLCDM024DCBAN is an ideal solution for facilities that need to maintain or expand legacy QUADLOG safety systems without the lead times or costs associated with new procurement — especially since the part has been discontinued by the original manufacturer. Each unit is inspected and tested before shipment, giving maintenance teams confidence that the module will integrate seamlessly into their existing rack infrastructure.

Whether you are replacing a failed card, building out a redundant control architecture, or stocking critical spares, this module delivers proven performance backed by real-world operational history. Its compatibility with the APACS+/QUADLOG ecosystem makes it a direct drop-in replacement, and its sturdy construction reflects the industrial-grade quality standards that the Siemens Moore product line was known for throughout its production life.
