Tektronix VX4357 Relay Switching Module

The Tektronix VX4357 is a C-size VXI relay switching module that provides 32 independently controlled single-pole, double-throw (SPDT) relays for signal routing in automated test systems. Each relay supports programmable switching delays from 0 to 65,535 ms and carries 5 A per contact, making it suitable for general-purpose switching applications. Individual relays or the entire bank can be programmed to open or close, enabling flexible signal path configuration within VXIbus compliant mainframes.
