Model SDVX33
VF
TRANSFER SWITCH
The SDVX33 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 SDVX33 VF Transfer Switch may be used in airport and other communication and control systems where passive static multiple channel A/B, main/stand-by signal switching is required.
The SDVX33, 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 SDVX33 unit. The SDVX33 features an individual read back circuit and an individual switching state indicator (bicolor LED) for each relay group. The transfer switching circuits and their controls are accessed from rear panel multi-position connectors.
The SDVX33 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.
