IZH2.390.042-46 remote control panel for Baklan-20

IZH2.390.042-46 is an aircraft remote control panel used for frequency selection and operating mode control of the Baklan-20 onboard VHF radio station. Depending on modification and aircraft configuration, similar panels may be referenced as PDU Block 4, IZH2.390.042-43 or IZH2.390.042-31. The panel is installed in the aircraft cockpit and provides the flight crew with direct access to radio station control functions during flight and ground operation.

Radio station control through IZH2.390.042-46

The IZH2.390.042-46 panel allows the crew to select working communication frequencies and control operating modes of the connected VHF radio station. It works as the cockpit interface between the crew and the main radio equipment installed outside the immediate control area. The panel is not a standalone radio device and does not transmit or receive radio signals by itself; it controls the connected Baklan-family radio station equipment through the aircraft wiring system.

Frequency setting and audio control

The panel provides frequency selection in the aviation VHF communication band by means of rotary / disk-type selectors. It also includes audio control elements, including a volume control for adjusting sound level in crew headsets or helmets. Depending on the specific modification, the panel may include controls for the noise suppressor function, allowing the crew to enable or disable squelch operation when no useful signal is received.

Indication and cockpit operation

The IZH2.390.042-46 remote control panel is designed for installation in the cockpit instrument panel or communication control area. The front panel may include built-in illumination for night operation and visual indication of radio operation modes, including receive and transmit status where applicable. This allows the crew to monitor radio operation without accessing the main transceiver unit installed in the aircraft radio equipment compartment.

Application with Baklan-20 and Baklan-5 radio stations

The IZH2.390.042-46 panel is used with Baklan-20 and related Baklan-family VHF radio stations, including Baklan-5 where applicable by aircraft documentation. Typical application may include aircraft and helicopters of civil aviation, including Mi-8 family helicopters and other aircraft equipped with compatible Baklan radio communication systems. Since panel versions may differ by illumination type and switching scheme, applicability should be confirmed by aircraft wiring and radio station documentation.

Identification and ordering of IZH2.390.042-46

The product may be referenced as IZH2.390.042-46, ИЖ2.390.042-46, PDU Block 4, Baklan-20 remote control panel or Baklan control panel. Related modifications may include IZH2.390.042-43 and IZH2.390.042-31. These versions may differ by illumination arrangement and switching configuration, including installations for single or paired radio station sets. For correct supply, it is useful to specify the exact modification, aircraft type, required illumination version, connector configuration, condition and documentation requirements.
