Description
Working Principle:
Each channel adopts dual circuit detection mode; continuously monitors signal circuit integrity; once abnormal circuit detected, send fault message to main controller and execute safety logic.
Technical Specifications:
- Channel Count: 16 safety digital channels
- Signal Voltage: 24 V DC
- Safety Integrity Level: SIL 3
- Operating Temperature: -40 ℃ ~ +70 ℃
- Protection Class: IP20
Function Features:
- Channel-wise open/short circuit diagnosis
- Galvanic isolation between field side and system side
- Support de-energize-to-trip safety design
Material & Structure:
- Plug-in cabinet module; terminal connector for field wiring
- Anti-corrosion conformal coating on PCB
Application Scenarios:
Emergency shutdown systems, fire & gas detection interlock, valve position feedback monitoring, safety barrier signal acquisition.
Installation Requirements:
Install inside safety control cabinet; Separate safety circuit wiring from non-safety circuit; Use shielded twisted pair for long-distance field wiring.
Usage Notes:
Do not mix safety and non-safety loads on the same module; Conduct periodic proof test according to safety loop requirements.
