Features

• Logic Solver Optimized: Specifically designed for the DeltaV LS safety platform to ensure deterministic processing of discrete safety signals.
• Integrated Excitation: Provides the necessary +24 VDC field power directly to the dry contact, simplifying field wiring and reducing external power distribution needs.
• Electronic Marshalling: Enables any signal type to be landed on any terminal block, allowing for rapid I/O reconfiguration without rewiring.
• Corrosive Environment Protection: Features a G3-rated conformal coating, making it highly resistant to airborne contaminants in aggressive industrial locations.
  
• Hot-Swap Capability: Allows for the replacement of individual modules while the rest of the safety system remains operational, minimizing downtime.
• Mechanical Coding: The 2C terminal block keying ensures that only compatible DI modules can be inserted into the base, preventing accidental hardware mismatches.
