RBI-1 Relay Buffer Interface

RBI-1 provides relay isolation between the transceiver and any amplifier. Mechanical relay is more robust than solid state switches and provides polarity independence  while limiting switching requirements to less than 5 ma from the transceiver. May modern transceivers with voltage and current limitations, cannot switch the voltage and current required to switch the amplifier. It runs on 11-15 VDC at only 40 ma. and will switch any  amplifier T/R relay up to 250 VAC at 5 A.
