Emerson

1.Main Functions

• Dry contact state acquisition: Detects open / closed status of field dry contact devices, including limit switches, push buttons, relay contacts and alarm contacts.
• 24VDC dry contact sensing: Provides internal 24VDC field sensing power for dry contact loops, detects contact closure without external power supply from field side.
• Signal conversion: Converts field contact on/off discrete status into digital data and transmits it to DeltaV controller via CHARM bus.
• Built-in channel diagnostics: Continuously monitors module health, channel fault and wiring abnormality; reports fault information to DeltaV DCS and AMS asset management software.
• Isolation & surge protection: Optical isolation and surge suppression between field circuit and control bus, prevents interference and circuit damage.
• Hazardous area safety design: Energy-limited circuit with ATEX / IECEx / FM certification for Zone 2 hazardous explosive areas.
• Hot swap capability: Plug-and-play CHARM module; can be replaced on compatible baseplate without shutting down the whole rack.

Core summary: This DeltaV CHARM digital input module collects on/off status of field dry-contact switches and relays, converts discrete contact signals into digital data for the DeltaV DCS to realize equipment status monitoring and interlock control.www.plcva.com
