Relays
Universal Relay Boards
Depending on the components used this board can replace any DPDT (double pole double throw) or 3PDT (three pole double throw) standard T/R relay. This board features accurate contact sequencing. It is usable in transmit-receive relay systems from 12Vdc to 120Vdc.
Switching time is typically <7mS make and 5mS break. The usable frequency range is dc to 60 MHz at full power of 2kW carrier ICAS on the output contacts.
$49 basic UNRS-12 12Vdc. Ameritron and other 12Vdc T/R relays
$59 basic UNRS-24 Drake L4 and L7 and other 24Vdc T/R relays
$59 basic UNRS-120 Heathkit, Collins, Kenwood, and other 120Vdc relays
Full kits with cables available. See this page link for examples
