BURKERT 20034183 is an 8-slot Type 8652 AirLINE valve island engineered for discrete control in process automation plants. This specific configuration features a stainless steel 1.4301 AirLINE Quick adapter plate, four pre-installed Type 6534 dual 3/2-way normally closed solenoid valve modules (circuit function C) on positions 1 through 4, and four blanking plates on positions 5 through 8. Pneumatic supply connection 1 is executed via D10 mm stainless steel push-in fittings, while working ports 2 and 4 are configured with D6 mm stainless steel push-in fittings. Communications are handled through an integrated Industrial Ethernet gateway supporting PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, and CC-Link IE Field Basic via two RJ45 connectors.

Type 8652 integrates an LC display that shows diagnostic and status messages in clear text and standardized symbols directly at the island, simplifying commissioning and on-site troubleshooting. Diagnostic telegrams are simultaneously transmitted over the fieldbus network to the supervisory PLC. The assembly is optimized for mechanical integration into control cabinet cutouts, providing IP65 ingress protection and NEMA Type 4X integrity when installed on enclosure walls or floors using the stainless steel AirLINE Quick interface.

AirLINE Quick Stainless Steel Adapter System

The AirLINE Quick system allows the pneumatic valve terminal to be fastened directly into a rectangular cutout on the control cabinet bottom or side wall. Compressed air tubing connects directly to the outside face of the enclosure, eliminating bulkhead fittings, internal tubing runs, and excessive wiring.

Pneumatic Fitting Material	Stainless steel 1.4401
Supply / Exhaust Ports	Push-in D10 mm (3/8")
Working Ports	Push-in D6 mm (1/4")
Mounting Location	Control cabinet floor or control cabinet wall
Ingress Seal	Tight seal to cabinet wall fulfilling IP65 and NEMA 4X

Installation Advantage

Direct mounting through the cabinet floor reduces enclosure volume requirements, cuts installation labour, and prevents internal air contamination within the electrical enclosure during line venting.

Circuit Functions

Article 20034183 contains four dual 3/2-way pilot valve blocks of circuit function C. Each 11 mm slice houses two independent 3/2-way valves serving ports 2 and 4.

Function Code	Valve Schematic	Description
CF C (Fitted)	2x 3/2-way solenoid valve	Servo-controlled, normally closed, equipped with manual override. De-energized state shuts off flow from supply (1) to ports (2) and (4), exhausting to (3) and (5).
CF D (Compatible)	2x 3/2-way solenoid valve	Servo-controlled, normally open, equipped with manual override.
CF H (Compatible)	5/2-way solenoid valve	Servo-controlled, with manual override. Supply pressure at port (1) pressurizes either port (2) or (4).
CF L (Compatible)	5/3-way solenoid valve	Servo-controlled, with manual override. In middle position, all ports are closed/locked.
CF M (Compatible)	5/3-way solenoid valve	Servo-controlled, with manual override. In middle position, ports (2) and (4) are pressurized.
CF N (Compatible)	5/3-way solenoid valve	Servo-controlled, with manual override. In middle position, ports (2) and (4) are exhausted.
CF Z (Compatible)	5/2-way impulse valve	Bistable double-solenoid impulse valve with 2 coils and manual override.

Positions 5, 6, 7, and 8 are covered by blanking plates (article no. 335779). They can be retrofitted with additional standard 6534 valves or SIA safety shut-off variants at any time.

Mechanical Dimensions and Cabinet Mounting

For an 8-slot terminal, the physical mounting envelope is governed by the 8-fold base parameters shown in the dimension drawing:

Terminal Size	Dimension A (mm)	Dimension B (mm)	Fastening Pattern C	Multiplier m	Multiplier n
4-fold	66	—	4x M5	3	1
8-fold (20034183)	35	111	8x M5	7	2
12-fold	77	154	10x M5	11	3

Alternative DIN-rail mounting is supported via standard rail EN 50022 (35 x 7.5 mm or 35 x 15 mm). When positioning the valve island inside the cabinet, observe maintenance clearances between the island and the enclosure door or side wall to allow manual operation and module extraction.

Electrical and Fieldbus Connections

Type 8652 uses distinct, galvanically separated power circuits for logic/communication and pneumatic coil actuation. Wiring is implemented using pluggable spring-loaded terminal connectors.

Logic and Display Power Supply (5-Pin Connector)

Connected via pluggable 5-pin spring terminal (article no. 920180, wire cross-section ≤ 1.5 mm²):

Pin / Terminal	Wire Colour	Signal Assignment
1	Red	+24 V DC (Electronics & Display)
2	White	CAN_H (büS interface)
3	Green	Shielding
4	Blue	CAN_L (büS interface)
5	Black	0 V DC (GND)

Pneumatic Valve Power Supply (2-Pin Connector)

Actuation power for pilot coils is routed through an independent 2-pin spring-loaded terminal (article no. 920442):

Pin / Terminal	Wire Colour	Signal Assignment
1	Red	AUX +24 V DC (Coil power supply)
2	Black	0 V DC (GND)

Power Separation Notice

The pneumatic valves and the primary communication/display logic must be powered from independent supplies or separate fused branches to ensure that an emergency trip of valve coil power does not interrupt fieldbus communication or diagnostic reporting.

Industrial Ethernet Dual RJ45 Interface

Article 20034183 includes an ME43 Industrial Ethernet communication module with two 100BASE-TX RJ45 ports (X1 and X2), providing an integrated Ethernet switch for line or ring network topologies.

Pin	Signal	Description
1	TX+	Transmit Data +
2	TX-	Transmit Data -
3	RX+	Receive Data +
4	N.C.	Not connected
5	N.C.	Not connected
6	RX-	Receive Data -
7	N.C.	Not connected
8	N.C.	Not connected

The module automatically supports PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, and CC-Link IE Field Basic. PROFINET S2 system redundancy is also supported to maintain plant availability during controller changeovers.
