Honeywell FC-SDIL-1608 SIL3 Digital Input

SIL3 Loop-Monitored Digital Input with 16 NAMUR Channels

The Honeywell FC-SDIL-1608 and FS-SDIL-1608 provide sixteen channels for loop-monitored inputs from proximity switches. 

Safety & Monitoring Features

• Designed for SIL3 applications up to IEC 61508 safety integrity level 3
• Sixteen channels for loop-monitored loops or NAMUR proximity switch signals
• Earth fault monitoring across all sixteen loops ensures system grounding integrity
• Signal conversion requires BN-1608 or BSN-1608 converter modules

LED Indication System

• Two LEDs per channel: Green shows channel status, Red indicates lead breakage or short circuits
• Earth LED: Green for OK earth connection, Red for false earth, OFF when disabled
• Status LED: Green for module OK, Red for faulty or not running
• Front-panel LEDs enable immediate visual diagnostics

FAQ

• Q: What is the difference between FC-SDIL-1608 and FS-SDIL-1608?
  A: FC-SDIL-1608 includes conformal coating for harsh environments. FS-SDIL-1608 is the standard version.
• Q: Why do I need BN-1608 converters?
  A: The SDIL-1608 requires these converters to condition NAMUR signals for the module.
• Q: How does earth fault monitoring work?
  A: The module injects test current and measures voltage. Green LED means good earth connection.
