AirLINE Quick Cabinet Floor Interface
BURKERT 20023497 incorporates the AirLINE Quick adapter plate, allowing direct mechanical cutout mounting through the control cabinet floor or wall. Pneumatic supply and working lines connect directly on the exterior underside of the cabinet, eliminating internal bulkhead fittings and saving installation space.
Advantages of AirLINE Quick
- Direct connection of pneumatic tubing to the cabinet base reduces cabinet envelope dimensions.
- Eliminates cabinet interior tubing clutter and secondary bulkhead pass-throughs.
- Provides IP65 protection rating into the cabinet interior when fastened using the integrated gasket and specified M5 fastening screws.
Circuit Functions and Valve Assignment
Positions 1 through 6 on 20023497 feature dual 3/2-way servo-controlled solenoid valves under Circuit Function C (normally closed). Each 11 mm slice contains two independent pilot seats controlling two separate working ports.
| Function Code | Valve Type | Description | Switching Times |
|---|---|---|---|
| CF C | 2x 3/2-way solenoid valve | Servo-controlled, normally closed, equipped with manual override | Opening: 15 ms Closing: 15 ms |
| Blind Plate | Dummy plate | Covers empty stations (positions 7 and 8) to maintain pressure integrity | — |
Each valve slice incorporates check valves in the common exhaust air ducts. These check valves isolate adjacent valves from exhaust pressure spikes during high-frequency switching, preventing uncommanded actuator movements.
Dimensions and Installation Clearances
BURKERT 20023497 is built on the 8-slot chassis format. The overall dimensions and mounting hole matrix comply with the standard Type 8652 engineering layout:
| Variant | Dimension A (mm) | Dimension B (mm) | Fastening Holes C | Distance Index m | Station Index n |
|---|---|---|---|---|---|
| 4-fold | 66 | — | 4× M5 | 3 | 1 |
| 8-fold (20023497) | 35 | 111 | 8× M5 | 7 | 2 |
| 12-fold | 77 | 154 | 10× M5 | 11 | 3 |
When mounting inside an enclosure, maintain minimum clearances between the terminal front and the cabinet door to permit tool access and Hot Swap valve removal:
Electrical Connections and Fieldbus Interface
Power supply and Industrial Ethernet communications enter the terminal through segregated connection interfaces.
Electrical Segregation
Supply electronics and pneumatic valves from independent circuits. The 2-pin spring-loaded terminal provides dedicated auxiliary 24 V DC power (AUX 24 V) to the solenoid coils, allowing emergency valve shutdown without dropping the fieldbus node or LCD display.
Power Supply Connections
