Dual Serial Remote Control Ports and
Dual Power Supply Ports
The Model 7283 4-Channel RS530 A/B Switch with DB25 Interface features Dual Serial Remote Control Ports and Dual Power Supply Ports. Two external power supplies are connected to the unit. Internal circuitry automatically regulates which supply will power the unit. If a supply is removed, the supply remaining powers the unit. Furthering reliability, all switched signals are passed via copper contact relays that maintain their position and continuity in during a power loss.
