Amplifier keying relay buffer interface SIX radios and 6 linear switching RBI-66

Choose one of SIX radios keys SIX amplifiers. High quality relay box to interface between. Any SIX amplifiers Switch chooses. Radios that will activate ALL SIX amplifiers or noise cancelling units (choose any unused switch position to bypass the amplifiers). Many newer radios can only provide for a small amount of current on the external amplifier keying output.

In response to your requests for a relay interface box that will key up to SIX completely separate amplifiers, we have developed the RBI-66. Do you have a need to key SIX amplifiers (perhaps a driver amp and high power amp, noise cancelling units, etc) that have different keying relay voltages?

The keying circuits in our RBI-66 are COMPLETELY SEPARATE from each other and the radio is isolated. EACH output is a relay closure from center conductor of the RCA jack to the outside of the RCA jack.

EACH output uses completely SEPARATE relay contacts! WHY use two or more amplifiers? Some users want to extend the life of their radio's expensive final transistors by running low power from their radio into an intermediate amplifier and have that amplifier run only what is needed to get full output from their higher power amplifier. Some users want to use an "instant on" amplifier for most contacts but still also have a larger amplifier what may require warm up time that is less frequently used. With our box, you do not need to reach in back to disconnect and reconnect each amplifier keying line. Some users have dedicated amplifiers for different bands and antennas and also don't want to to disconnect and reconnect individual relay keying cables. RCA jacks in and out Needs 9-15 VDC at only 130 ma.

5 feet of wire included. Connect our RBI-66 to your radios keying circuit (ground center conductor to key our box) Connect your amplifier relay keying input to any output on our RBI-66, connect your other amp keying line to another RBI-66 output. Relays rated up to 240 Volts at 5 AMPS, switch AC or DC any polarity! Genuine relay used for switching (not an easy to damage solid state device) ALL amplifiers switch at the same time ALL amplifier keying lines are completely isolated from each other This is for radios that can provide a closure of contacts to key this interface and for amplifiers requiring a closure of contacts to complete the T/R relay circuit inside the amplifier. 100% hand made and tested by Hams for Hams in Colorado.

Style of knob MAY vary. This is not one of those types that make you use a battery to power the unit! This high quality device is powered by your station power supply or any filtered DC source from 9-15 VDC (only 65 ma required) Need the best DC power supply? Need to key only one amplifier? Need to key up to SIX amplifiers from one or two radios? Need to key 2 or 4 linears? See our listing for RBI-62. (6 radios to 2 amplifiers) or the RBI-64 (6 radios to 4 amplifiers). (We also have a SIX unit amp keying box, keyed from a single radio). When connecting your Radio and Amplifier, there may be switching voltage, polarity, and current incompatibility that can cause damage to your radio or amplifier if connected without a switching interface between them. Even if your internal radio switching looks like it might be usable, it is wise to have an extra degree of isolation between your amplifier and radio with our relay buffer interface.
