Model SDVX-3
VF TRANSFER SWITCH
The SDVX-3 VF Transfer
Switch is a multiple channel A/B switching instrument designed for airport fiber optic
communication system applications. It routes electrical signals within the FAA
communication and control loop to either the clockwise or the counter clockwise system.
The SDVX-3 VF Transfer Switch can be used in airport and other communication and control
systems where passive static multiple channel A/B signal switching is required.
The SDVX-3 consists of 24 high quality, low contact resistance double pole double throw, two coil latching relays. They are organized in 3 groups of 8 relays each. Each group has an independent SET and RESET (or A and B) control. These relays provide switching for a total of 48 signal channels for each SDVX-3 unit. Additionally there is a read back relay in each group. The switching circuits and their controls are accessed from rear panel multi-position connectors.
The
SDVX-3 VF Transfer Switch is a passive multiple channel switching system which requires
external power only when the relay coils are being momentarily driven to initiate a state
change.
