EX1200-2007A Datasheet
48 channel 1000 V Multiplexer
|
Overview
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.
A
fail-safe interrupt line is provided on the front panel that can be used when switching high-voltage source/measure units, or power supplies. This interrupt can be programmed to open up all relays automatically in the event of a fault condition and, thus instantly removing power from the user interface.
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.
