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 along with parallel 2X 8-ampere gold-plated RF tested output contacts.
We build this relay to fit 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. The output relay safely handles 2kW standard ICAS carrier duty on 6 meters, increasing to 4kW below 30 MHz. (Peak power rating is higher.) This board normally comes in a version with ground bus and space for a buffer transistor.
It is 2″x1.8″x1″ tall.
For tight spaces, we have a smaller UnRS-C board that is 1.5″ wide x 1.75″ deep x less than 1″ tall.
