The EX1200-3048 is a high-density multiplexer modules designed for scanning of multiplepoints to a common bus, in either 2- or 4-wire configurations. Applications include cable harness testing, temperature/voltage monitoring, PCB testing, and those in which multiple points need to be switched to a common resource. Each path allows for hot switching of up to 300 V and 2 A (60 W max), and two dedicated channels have the capability to directly measure current up to 3 A using the integrated EX1200 DMM.
The EX1200-3048 consists of dual (1×24) 2-wire multiplexer banks. Each bank can be interconnected within a module under program control (via bussing relays) to form a 1 x 48 multiplexer. The EX1200 analog bus can be used to configure larger multiplexers, which eliminates external wiring and helps reduce unterminated stub effects. Up to 288 two-wire (or 144 four-wire) channels can be accommodated in a single EX1200 full rack mainframe for maximum density or mixed and matched with other EX1200 plug-ins for flexibility.
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.
