The 20-519A series of 40 x 4 matrix modules are available with either 1 or 2 pole switching. Built-in features include automatic isolation switching, plug-in expansion using internal analogue bus and relay contact self-test to give complete switching confidence. This matrix module with it ’s “long and narrow ” 40 x 4 configuration is designed for easy construction of small to medium sized matrix switching systems. Typically for use in small ATE systems where up to four source or sense instruments need to be connected to a device-under-test or bed of nails. Modules may be easily expanded to form matrices of almost any size,e.g.80 x 4,120 x 4,..320 x 4,..etc.
