Description
The SDA All Relay Control Board is the all inclusive relay control board for the SDA 100 and OptimizIR 2.0 controller. This relay board features the 3 relays controllers needed to operate the DB style antennas and includes the amplifier lock-out. The lock-out circuit connects via PTT cable to they key of the RF power source and prevents the amplifier from transmitting while the SteppIR antenna is being tuned. Helps prevent potential mismatch issues that could damage the antenna.
New and Improved design!
- Can handle a dead short condition on the relay control lines
- Withstands over 5kV coupled to control lines
- Reduced RF Noise from new design
