Important Notes

1. Discrepancies in Specifications:
   • Some sources describe this as an 8-channel module or mention 220 V AC compatibility, likely referencing variant configurations or relay switching capacity. Always verify with Emerson’s official documentation.
   • Voltage ratings (24V DC vs. 48V DC) and communication protocols (Modbus RTU vs. Ovation proprietary) may vary by region or application.
2. Critical Applications:
   • For hazardous environments, request explosion-proof variants (e.g., 1C31219G01-EX) from Emerson.
   • Firmware updates must be performed using Ovation Configuration Studio to ensure compatibility with the DCS.
3. Support Channels:
   • Emerson Process Automation: +1-800-EMERSON (North America) or local regional offices.
   • Distributor Network: Use Emerson’s online portal to locate certified Ovation partners.
