Unconnected inputs float
Unconnected inputs typically float high, but not reliably. If you are using a
TTL to solid state relays
Many applications require digital outputs to switch AC and DC voltage motors on and off or to monitor AC and high DC voltages. These AC and high DC voltages cannot be controlled or read directly by the TTL digital lines of a
Solid State Relays (SSRs) allow control and monitoring of AC and high DC voltages and provide 750 V isolation. SSRs are the recommended method of interfacing to AC and high DC signals.
The most convenient way to use solid state relays and a
