Product Description
DC-TAOX11 51307605-176 is a 24 VDC digital input module of Honeywell Series‑C I/O family for Experion C300 DCS system. It acquires discrete signals from field switches, proximity sensors and relay contacts; configurable for NO / NC contact types. Channel‑group isolation and built‑in self‑diagnosis detect circuit faults. Hot‑swap supported, rack‑mounted on C300 I/O backplane. Widely used for discrete signal acquisition in petrochemical, oil‑gas and power process plants, serving as spare part for maintenance and legacy‑system replacement.
