EX1200-3072

  • High-density 300 V/2 a multiplexing scanning (up to 432 two-wire channels in 1U footprint)
  • Two individual (1x36) 2-wire multiplexer banks programmably combinable to form a 1x72 multiplexer
  • Configure as 2- or 4-wire multiplexers
  • Internal capacitive discharge relays keep high voltages from disturbing sensitive measurement points
  • Supports thermocouple, RTD, and thermistor measurements
  • Optional screw-terminal junction box includes built-in cold-junction compensation
  • Direct routing to DMM through internal analog measurement bus simplifies field wiring
  • OVERVIEW +


    The EX1200-3072 high-density multiplexer module is designed for scanning of multiple points to a common bus in either 2- or 4-wire configurations. Applications include cable harness testing, semiconductor and PCB testing, and those in which multiple points need to be switched to a common resource.

    The EX1200-3072 consists of dual (1x36) multiplexer banks. Each bank can be interconnected within a module under program control (via bussing relays) to form a (1 x 72) 2-wire mux. The EX1200 analog bus can be used to configure larger multiplexers as required to eliminate external wiring and helps reduce unterminated stubs effects. Up to 432 two-wire (or 216 four-wire) channels can be accommodated in a single EX1200 full rack mainframe.

    An optional terminal block provides screw termination points for external field wiring. This terminal block also includes cold junction compensation reference for more precise temperature measurements.
