Emg 22 diode blocks. Diode circuits perform various tasks in electrical and electronic control systems like electrical decoupling of messages in fault signalling systems or as spark-suppression diodes for limiting surge voltages of inductive loads, such as solenoid valves or DC relays. In order to meet these requirements, diode modules are available as "diode gates" with common negative and positive polarity or as individual diodes.
