Siemens Moore QLODM115ACBBN

Siemens Moore QLODM115ACBBN is a high-reliability discrete input module built for QUADLOG and APACS+ distributed safety control systems. This discrete input module collects 24VDC digital signals from limit switches and interlock sensors. This discrete input module transmits digital status data to the critical control module via backplane bus. This discrete input module supports channel fault diagnosis and signal isolation protection. This discrete input module detects open and short-circuit faults of each signal channel.

The module adopts rack-mounted compact board structure and built-in surge protection. As an essential digital signal acquisition unit, it monitors on-off status for petrochemical, power and boiler safety interlock loops. The digital signal acquisition unit filters electromagnetic interference to guarantee stable signal quality. The digital signal acquisition unit matches different types of field discrete sensors. The digital signal acquisition unit quickly reports channel failures for plant maintenance.

This spare part is designed for hazardous area certification and long continuous operation. As robust DCS discrete I/O hardware, it resists vibration and temperature fluctuation inside control cabinets. The DCS discrete I/O hardware supports hot swap for online replacement without plant shutdown. The DCS discrete I/O hardware uses high-density connectors for stable backplane communication. The DCS discrete I/O hardware serves as an ideal replacement for aging QUADLOG discrete input hardware on production lines.
