The EX1200-3164 high-density multiplexer module is designed to provide a flexible switching multiplexing architecture with 16 individual 1×4 2-wire multiplexers. Up to 96 1 x 4 two-wire channels can be accommodated in a single EX1200 full rack mainframe. Applications include cable harness testing, semiconductor and PCB testing, and those in which multiple points need to be switched to a common resource.
All relays also have individual control, and each path allows for hot switching of up to 300 V and 2 A (60 W DC max). Each bank can be interconnected within a module under program control (via bussing relays) to form larger 2-wire muxes, up to a maximum of 1×64. The EX1200 analog bus can be used to configure larger multiplexers across modules as required to eliminate external wiring and helps reduce unterminated stubs effects. The analog bus can also be routed directly to the optional EX1200 series 6.5 digit DMM for direct measurements across the backplane further reduce external wiring.
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
