The Honeywell 8C-SDOX01 is a rugged, coated relay extension board within Honeywell’s Series 8 Experion-LX I/O family. Designed to convert Honeywell digital output modules (DO IOMs) into isolated dry-contact relay outputs, it offers 32 Form-C SPDT channels with LED status indicators, enabling reliable interfacing with high-voltage or high-current devices. Engineered for harsh environments, it supports hot-swap insertion/removal and maintains signal isolation and durability in mission-critical control systems.Honeywell 8C‑SDOX01 DO Relay Extension: 32 isolated Form‑C relays, 250 VAC/125 VDC, coated for harsh environments, hot‑swap enabled, Class I Div 2/Zone 2 rated.
