Burkert 20040562 SVVI electrical base module is designed for the Type 8644 valve island system. Featuring an 11 mm width per station, this module is utilized for the electrical connection and control of pneumatic solenoid valves in distributed industrial environments. The Type 8644 system allows electronics assemblies and armatures to be easily and efficiently combined due to its modular assembly.

System Overview: Type 8644

Type 8644 is an electrical and pneumatic automation system that has been optimized for use in the control cabinet or switch box. All electronic and pneumatic components are standardized in a continuous system, so that pneumatic, electric and electronic modules with different functions can be combined very easily with each other, if simple rules are followed.

Electronic Base Module Type 8644

For type 8644, there are electronic base modules with slots for 2 or 8 valves. The electronic base module is part of the valve unit. It contains the electric plug connections for the valves and the electronics assembly for controlling the valves.

Disassembling/Installing Electronic Base Module Type 8644

Safety Instructions

• High pressure and escaping medium: Switch off the pressure before working on the modules, device or system. Vent or empty the lines.
• Electric shock: Before working on the modules, device or system, switch off the power supply. Secure it against reactivation.
• Electrostatically sensitive components (ESD): The units contain electronic components that are susceptible to the effects of electrostatic discharging. Do not touch electronic components when the supply voltage is connected.

Disassemble electronic base module:

1. Loosen the 2 fastening screws of each valve with a cross-tip screwdriver and remove the valves from the valve unit with the flange seal.
2. Loosen both latch hooks on the back of the pneumatic base module (e.g. with a slotted screwdriver).
3. Remove electronic base module from the pneumatic base module in the direction of the arrow.

Install electronic base module:

Installation is carried out in the reverse order to disassembly.

1. Slide electronic base module onto pneumatic base module in the opposite direction of the arrow until it comes to a stop. The latch hooks must engage with the lock.
2. When reinstalling the valves on the valve unit, note that the flange seal must be inserted correctly into the valve. Tighten the fastening screws of the valves crosswise.
