Specifications

The CY/8x8 is a general purpose, bidirectional reed relay matrix. It is a true non-
blocking matrix, and each input can be connected to one, many or all outputs
concurrently. All CYTEC VXI Modules utilize both Message and Register based
operation.
The CY/8x8 supplies two individual 8x4 matrices. These
can be interconnect externally by the user to provide one
8x8 or one 16x4 matrix. This VXI Switch Module is built
with 64 Reed Relays and is available in either single or
two pole versions, and with Type S Standard or Type M
Mercury reeds. It is also available as a two pole matrix
with Type LT Low Thermal reeds. Any number of relays
can be energized concurrently, and the status of all re-
lays may be read at any time.
