High Voltage Dry Reed Relays For up to 10kV
Series 67 & 68
Series 67 PCB mounting with switch and coil connections in a Single-in-Line format.Series 68 PCB connections on the underside for coil connections. Flying leads from the top face for high voltage connections.The Series 67 and 68 are constructed using former-less coils. The absence of a coil supporting bobbin allows a device smaller than the industry norm. The unusual package design gives some interesting possibilities for high density packing.The option of flying leads for the high voltage connections makes it possible to keep this away from lower voltage circuitry on the pcb.Form A (energize to make) contacts are available with the option of 5, 12 and 24 volt operating coils.

80 Channel Relay Multiplexer
DP-VXI-4017
DP-VXI-4017 is an 80 Channel Relay Multiplexer constructed using ‘2 Form A’ (DPST) relays. It is a ‘C’ size 1 slot register based VXI module. This 80 Channel Relay Multiplexer module is highly configurable. As an 80 channel multiplexer, one input can be multiplexed to any of the 80 outputs or vice versa. The 80 channel multiplexer is divided into 8 banks of 10 channels each. This combination allows the board to be used as one group of 80x1 or two groups of 40x1 or four groups of 20x1 or eight groups of 10x1 differential multiplexer. The banks are isolated from each other by tree switches. 8 tree switches are used, one tree switch for each bank. A common tree switch is used to group all the eight banks. For short circuit protection resistors are provided for all the common terminals.
