Information About DX-9121-8454
The DX-9121-8454 belongs to the Metasys DX-9121 series of LONWORKS digital controllers and uses an FTT-10A LONWORKS interface. Its analog inputs support 0β10 VDC, 0β20 mA, and RTD sensors, while the analog outputs support 0β10 VDC or 0/4β20 mA signals. The controller also provides eight dry-contact inputs and six 24 VAC triac outputs rated at up to 0.5 A. Johnson Controls identifies the DX-9121 series as a legacy Metasys controller family; its listed global end-of-support date was July 2026.
Key Features:
- LONWORKS Digital Controller: Provides programmable control for building automation and HVAC systems.
- Eight Analog Inputs: Accepts 0β10 VDC, 0β20 mA, and compatible RTD sensor signals.
- Eight Digital Inputs: Provides dry-contact inputs for monitoring connected devices.
- Four Analog Outputs: Supports 0β10 VDC and 0/4β20 mA control signals.
- Six Triac Outputs: Provides 24 VAC digital outputs rated up to 0.5 A.
- FTT-10A Interface: Provides LONWORKS communication for compatible building automation networks.
- Local Display: Includes an integrated display panel for local controller operation and monitoring.
- Extension Support: Supports compatible XT/XP extension modules for additional control functionality.
The DX-9121-8454 provides configurable I/O and LONWORKS networking for compatible Metasys HVAC and building automation installations.
