Formerly Radiodan




 Amplifier Keying Relay Interface:
  • RCA jacks in and out
  • Runs on 9-15 VDC at only 40 ma
  • Will switch any amplifier keying line up to 120 VAC at up to 3 amps.
  • DC power cord, +/-5Ft included

 A high quality keying relay that is intended as an interface between any radio and your amplifier (RBI-1) or any radio and two amplifiers (RBI-2). Protect your expensive transceiver from high relay control voltage, voltage spikes, or excessive current draw from your amplifier. The RBI-x will key most any amplifier. Many newer radios can only provide for a small amount of current on the external amplifier keying output. The RBI-x will draw 0.3 MA and will key any amplifier.
