4-CHANNEL ANTENNA SWITCH CONTROLLER MODULE – 7 OPERATING MODES

This module is designed for manual control of antenna switches and other 12–28 V DC devices.

It features 4 independently controlled outputs, each capable of switching up to 1 A. The outputs are controlled by low-resistance power MOSFETs, making the module suitable for a wide range of antenna switching and other control applications.

Key Features

• 4 independently controlled outputs
• Up to 1 A per output
• 7 different operating modes, selectable using solder jumpers
• Supply voltage: 7–28 V DC
• Output voltage: same as the supply voltage
• Low-resistance output MOSFETs with RDS(on) < 50 mΩ
• Sensitive piano-style push buttons for manual control
• Individual LED indicators for output status
• Presettable initial state of each output using solder jumpers
• Compact size: 60 × 40 mm
• Convenient spring-cage terminal connectors for quick and secure wire connection
• Modern low-power microcontroller
• Ready-to-use and fully tested

Operating Modes

The module includes 7 pre-programmed operating modes.

The desired mode is selected using solderable jumpers on the PCB.

The complete description of the operating modes and jumper settings is shown in the listing photo gallery.

A video demonstrating the module and all 7 operating modes is also included in the photo gallery.

Custom Configuration

I can configure and solder the jumpers before shipping according to your requirements.

Simply let me know which operating mode and initial output states you require.

Custom software modifications are also possible according to your requirements. Software modifications are available for an additional fee. Please contact me before purchasing if you need a custom function.

Applications

The module is primarily intended for:

• Amateur radio antenna switching
• HF / VHF / UHF antenna systems
• Remote antenna switches
• Relay and MOSFET switching applications
• Manual control panels
• Other low-voltage DC switching applications

Package Contents

Included:

• 1 × ready-to-use and tested 4-channel controller module

Not included:

• Power supply
• Wiring or other accessories

Important Notes

The module switches the same DC voltage as the supply voltage. The maximum current is 1 A per output.

The module is supplied ready assembled and tested. No soldering or programming is required unless you want a different jumper configuration or a custom software modification.

Please see the photo gallery for the schematic, jumper configuration, operating modes and demonstration video.

Designed for reliable and flexible control of antenna switching systems and other 12–28 V DC applications.
