Product Details:

SIEMENS QLRTMBAN is a dedicated RTM resistance temperature acquisition module built for QUADLOG and APACS+ DCS rack systems, designed to receive and process RTD resistance signals from PT100 and other resistance temperature sensors installed on site. It converts the resistance variation caused by temperature change into digital signals, then transmits accurate temperature measurement values to the main control module for closed-loop temperature regulation, over-temperature alarm and process data recording. The module adopts industrial reinforced PCB and full EMC shielding structure, with built-in surge protection and signal isolation circuits, which can effectively suppress electromagnetic interference and ground loop noise in the control cabinet, ensuring high-precision temperature sampling even under long-term continuous operation.

It uses standard backplane plug-in installation design, supporting quick disassembly and replacement during on-site troubleshooting and scheduled maintenance, which greatly reduces the downtime of temperature control loops. The module supports multiple RTD types and signal range configuration through APACS+ engineering software, and integrates independent channel fault diagnosis function, capable of detecting sensor open circuit, short circuit and signal abnormal state, and uploading alarm information to the host in real time for rapid fault location. Every spare unit will pass full channel temperature calibration, bus communication test and rack compatibility inspection before shipment to guarantee stable matching with original QUADLOG hardware. It is widely stocked as emergency replacement spare parts and I/O expansion components for temperature monitoring loops in legacy process automation systems.

Industry Applications: Applied in petrochemical auxiliary skids, gas flow control systems, boiler closed-loop control rooms and water treatment facilities for conventional analog signal acquisition and valve regulating output.

Note: Confirm SAM combined I/O feature and hardware revision before ordering
