Important Notes:

1. Dual-Redundant Configuration:
   • For dual-redundant setups, an additional module with the same specifications is required.
2. Signal Cable Compatibility:
   • When using this module with signal cables, specific option codes (/SDV531, /SDV53L, or /DV53L) must be selected to prevent incorrect module insertion.
3. Recommended Connections:
   • Use AKB331 or AKB651 signal cables for optimal performance.
   • Floating the field power supply is recommended for higher noise immunity.
