Data sheet
1Description
Diode circuits perform various tasks in electrical, but
especially electronic control systems, such as:
– Electrical decoupling of messages in fault signaling
systems
or
– As spark-suppression diodes for limiting surge voltages
of inductive loads, such as solenoid valves, DC relays
or similar
In order to meet these requirements, diode modules are
available as "diode gates" with common negative and
positive polarity or as individual diodes.
NOTE:
Please note that there is no isolation between the individual diode paths within a module.
Make sure you always use the latest documentation.
