BURKERT 20138039 (Type 8652 AirLINE) is a factory-configured 24-station pneumatic valve terminal engineered for process automation integration. Built with a stainless steel AirLINE Quick interface plate and a 24 V DC fieldbus communication architecture, article 20138039 features 24 fully populated valve slots equipped with 5/2-way bistable pilot solenoid valves (Circuit Function Z). The terminal integrates multiprotocol Industrial Ethernet communications over dual RJ45 ports (X1 and X2), enabling deployment across PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, and CC-Link IE Field Basic environments without altering hardware.
Designed for direct mounting through the bottom or side wall of control cabinets, this variant incorporates stainless steel D10 pneumatic supply connections, stainless steel D6 working ports, and a dedicated pneumatic intermediate supply module positioned centrally within the 24-valve bank. Electrical feed paths are segregated into an independent 5-pin spring-loaded supply for the communication module and a 2-pin spring-loaded auxiliary 24 V DC feed for the pneumatic valve coils.

AirLINE Quick Mechanical Integration
Article 20138039 incorporates the AirLINE Quick mounting adapter in grade 1.4301 stainless steel. This interface eliminates internal cabinet tubing bulkheads by allowing the valve island base to seal directly against a cutout in the control cabinet floor or wall. Pneumatic lines connect externally via push-in stainless steel 1.4401 fittings, shielding the cabinet interior from air line routing.
Dimensional Data for 24-Fold Terminal with Intermediate Supply
Dimensions below apply to the 24-slot terminal assembly with intermediate supply module as defined by Burkert manufacturing drawings (all values in mm unless stated otherwise):
| Configuration Variant | A (mm) | B (mm) | C (Fasteners) | D (mm) | m (Valves Left) | m' (Valves Right) | n (Mounting Holes) |
|---|---|---|---|---|---|---|---|
| 24-fold with intermediate supply | 156 | 312 | 10 × M5 | 158.3 | 11 | 11 | 6 |
| Width per individual station | 11 mm | — | — | — | — | — | — |
Mechanical Cutout Dimensions
When planning enclosure floor cutouts for 24-fold AirLINE Quick assemblies with intermediate supply, mounting hole spacing follows dimension B (312 mm) with intermediate mounting spacing dimension D at 158.3 mm. Fastening requires metric M5 screws with a minimum clearance of 10 mm through the cabinet baseplate.
Pneumatic Circuit Functions and Valve Type 6534
All 24 positions of article 20138039 are populated with bistable 5/2-way servo-assisted impulse solenoid valves (Circuit Function Z / CF Z). Each valve operates using two opposing pilot coils and features mechanical manual overrides (latching and spring return).
Circuit Function Z Characteristics
- Operation: 5/2-way bistable impulse switching; supply pressure applied at port 1 maintains pressure at working port 2 or working port 4 until an electrical impulse shifts the spool.
- Nominal Diameter: 4 mm.
- Flow Rate: QNn = 290 l/min air.
- Pressure Range: Vacuum to 10 bar (with internal auxiliary pilot supply maintained between 3 and 10 bar).
- Replacement Component: Burkert replacement valve Type 6534 CF Z, Article no. 301377 (includes mounting screws).
Pilot Pressure Requirements
Internal auxiliary pilot feed channels distribute pilot pressure across the manifold rail. Ensure the primary pneumatic supply line delivers at least 3.0 bar continuous pressure to guarantee prompt spool shifts on bistable 5/2-way valves.
Electrical and Fieldbus Connectivity
Electrical connection to article 20138039 is handled via separate power supply terminals and two shielded RJ45 female ports located on the integrated communication module.
Fieldbus Interface RJ45 (Ports X1 and X2)
The Industrial Ethernet hardware supports line and ring topologies across PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, and CC-Link IE Field Basic.

Power Supply Terminal Assignments
Communication and Display Power (5-pin spring-loaded terminal):
- Red: 24 V DC
- White: CAN_H (büS connection)
- Green: SHIELDING
- Blue: CAN_L (büS connection)
- Black: GND (0 V DC)
- Maximum wire cross-section: ≤ 1.5 mm²
Pneumatic Valve Supply AUX (2-pin spring-loaded terminal):
- Pin 1 (Red): AUX 24 V DC
- Pin 2 (Black): GND (0 V DC)
- Maximum wire cross-section: ≤ 1.5 mm²
Power Separation
Isolate the valve coil power supply (AUX 24 V) from the electronic bus logic supply. This electrical isolation prevents electromagnetic switching feedback from perturbing fieldbus communications and allows emergency safety shutdown of the valve coil bus without dropping network communications.
System Architecture and Network Configuration
Article 20138039 functions as a direct fieldbus slave terminal or as a primary master valve terminal bridging subordinate büS valve islands via its local CAN-based expansion bus.
Commissioning, parameter configuration, and diagnostic monitoring are conducted using the Bürkert Communicator software (Type 8920) via a PC connected through a USB-to-büS adapter. The software allows real-time viewing of valve cycle counts, coil status, and diagnostic flags.
