7 TTL TO SOLID STATE RELAYS

High AC and high DC voltage devices cannot be controlled directly by the outputs

of a CIO-DOxxH.

Solid State Relays are used control and monitoring of AC and high DC voltages.

They can provide up to 4000V of isolation. Solid State Relays (SSRs) are the

recommended method of interfacing to AC and high DC signals.

The most convenient way to use solid state relays and a CIO-DO##H board is to use

a Solid State Relay Rack. An SSR Rack is a circuit board that has sockets to accept

SSRs.

A variety of SSR modules and racks are available from Measurement Computing
