12.5 Conversion of the valve zone

For an explanation of the symbols for the valve zone components, see
section g 12.2. Valve zone.
Impermissible, non-compliant expansion!
Any expansions or reductions not described in these instructions interfere with
the basic configuration settings. This will prevent a reliable system configura-
tion.
1. Observe the rules for the expansion of the valve zone.
2. Observe the specifications of the system owner as well as any restrictions
resulting from the overall system.
You may use the following components for the expansion or conversion of the
system:
• Valve driver with base plates
• Pressure regulators
• with base plates
• Pneumatic supply plates with bridge card
• Electrical supply plates with supply board
• Pneumatic supply plates with UA-OFF monitoring board
See g Fig. 22.
With valve drivers, combinations of several of the following components are pos-
sible:
• Valve driver, 4x, with two base plates, 2x
• Valve driver, 3x, with one base plate, 3x
• Valve driver, 2x, with one base plate, 2x

Characteristics of the I/O module
• 8x digital input channels
• 8x M8 connections
• 24x digital output channels
• 1x D-SUB plug, 25-pin
• 2x analog output channels
• 2x analog input channels
• 2x M12 connections
• Additional actuator voltage connection
NOTICE
If you would like to operate the valve system as a stand-alone system,
a special right end plate is required, see section g 15. Accessories.

12.5.1 Sections

The valve zone of a valve system can consist of multiple sections. A section al-
ways starts with a supply plate that marks the beginning of a new pressure or
voltage zone.
An UA-OFF monitoring board should only be installed after an electri-
cal supply plate, otherwise the actuator voltage UA is monitored be-
fore supply.
