FET Switch Buffers
These open-drain FET buffer modules are intended for converting Deltang receiver 'P' outputs to type 'F'. The 'P' output is 0V when OFF and 3V when ON and can supply a maximum of 20mA on Rx6 receivers. Some receivers (e.g. Rx65 have 'F' outputs which provide a 'switch to ground' circuit with a 2A capability.
Most of the Rx6 receivers (Rx60, Rx61, etc) have no 'F' outputs. This creates a problem if you need to control 12V light bulbs or trigger a sound module. Many sound modules have more than 3V on the trigger input and this could damage the receiver microprocessor. The solution is to use one of these tiny add-on modules.
The buffer input connects to the 'P' output and the load is wired in-between the buffer output and the load positive supply, which can be up to 30V. Although designed for use with Deltang land-based receivers, these FET switches can be used where a low-level logic signal is required to switch a high current / high voltage load.
An open-drain FET buffer for converting Deltang 'P' outputs to 'F' - e.g. for switching external circuits. Supplied with 100mm leads for input, output and negative/ground connections.
A dual open-drain FET buffer for converting Deltang 'P' outputs to 'F' - e.g. for switching external circuits. Supplied with 100mm leads for input, output and negative/ground connections.
