ULTIPLEXER
The EX1200-2007A is designed for scanning multiple high-voltage points to a common bus in
either 1- or 2- wire configurations. It consists of two individual (1 x 12) 2-wire multiplexers, or
dual (1 x 24) 1-wire multiplexers that can be interconnected under program control (via bussing
relays) to configure larger multiplexers as required. This reduces the need for external cabling and
helps reduce unterminated stub effects.
When switching high voltages, the need for signal shielding becomes critical. The EX1200-2007A
has been designed to include large shield planes that reduce crosstalk and voltage spikes to
adjacent channels.
Up to 144 2-wire channels can be accommodated in a single EX1200 series mainframe for
maximum density, or combined with other EX1200 series modules to create a flexible system
switch.
