BURKERT 20136339 (Type 8652) is an electro-pneumatic valve island configured with a 20-slot AirLINE Quick stainless steel base, designed for process automation environments. All 20 valve stations are fitted with Type 6534 servo-controlled 3/2-way solenoid valves in circuit function C (normally closed), providing independent actuation for single-acting pneumatic actuators and process valves. The island communicates via PROFIBUS DPV1 using a standard Sub-D 9-pin interface and integrates 5 electronic input modules providing 40 digital inputs for direct field limit-switch and sensor feedback.

Pneumatic reliability is supported by integrated check valves in the exhaust ducts 3 (R) and 5 (S), which stop backpressure surges from causing accidental valve actuation. The island includes a pneumatic HotSwap function at supply port 1 (P), allowing individual pilot valves to be replaced during live plant operation with only an approximate 3% flow reduction. Process connections feature a stainless steel D10 mm push-in main supply port and stainless steel D6 mm push-in working ports, supplemented on the left module by threaded G 1/4" and M7 ports.

AirLINE Quick Adapter System

AirLINE Quick allows the valve island to mount directly into the cutout of a control cabinet floor or wall, eliminating bulkheads, separate pass-throughs, and internal cabinet tubing. Burkert 20136339 utilizes a mechanical adapter plate made of stainless steel 1.4301 equipped with stainless steel 1.4401 push-in connectors. Working lines route outside the enclosure, protecting sensitive electronics from process-side hose stress.

Electrical Connections & PROFIBUS DPV1 Interface

Power supply and communication lines are routed through separate terminal connections on the interface plate to keep pneumatic coil switching currents isolated from the logic bus.

24 V DC Power Supplies

• Logic & Display Supply (5-pin spring-loaded terminal): Connect 24 V DC to Red, 0 V DC (GND) to Black. Accommodates wire cross-sections up to 1.5 mm².
• Pneumatic Valve Supply (2-pin spring-loaded terminal): Terminal 1 (Red) receives AUX 24 V DC; Terminal 2 (Black) connects to GND. Coils operate on independent AUX power.

Bus Termination

When Burkert 20136339 is placed at the physical start or end of a PROFIBUS segment, active bus termination must be provided via the +5 V (pin 6) and DGND (pin 5) connections using standard RS-485 termination resistor networks.

Pneumatic Functions & Control Cabinet Installation

Burkert 20136339 features integrated check valves in exhaust ducts 3 (R) and 5 (S). These check valves prevent cross-pressurization and unexpected actuator movement caused by downstream backpressure peaks when several large cylinders exhaust simultaneously.

HotSwap Enclosure Clearance

To use the pneumatic HotSwap function and replace valves without interrupting main pressure supply 1 (P), maintain adequate clearance between the front of the valve island and the control cabinet door or front frame. Refer to the mounting diagram and ensure unhindered valve extraction during maintenance.

Commissioning with Bürkert Communicator

Parameter setting, diagnostic error readout, and mapping of cyclic PROFIBUS process values can be performed using the Bürkert Communicator software (Type 8920) in conjunction with the USB büS interface set (Article no. 772426).
