Key Functions

1. Illuminated momentary manual operation
    
   Amber lamp lights up when 120V power is applied to the lamp circuit; momentary NO contact closes while pressed, sends trigger signal to PLC digital input for start, jog, reset functions.
2. Washdown industrial sealing
    
   4X rated housing resists water splash, dust, chemical mist, suitable for food, beverage, water treatment and outdoor factory cabinet panels.
3. Modular expandable design
    
   Supports stacking additional contact blocks (add NC safety contacts) for dual-channel safety circuits paired with 440R-N23126 safety relay.
4. Visual equipment status indication
    
   Constant amber illumination indicates equipment ready/auto mode; lamp off signals fault/stop state for on-site operator quick identification.
5. Universal panel compatibility
    
   Standard 30mm cutout fits all standard industrial control cabinet doors, compatible with existing 800T/800H series button mounting hardware.
