Multiplexer switch modules up to 1000VDC in a 1, 2 or 4 wire configurations.

The EX1200-3001 and EX1200-3001DS are high-density multiplexer modules designed for scanning of multiple points to a common bus, in 1-, 2-, or 4-wire configurations. Applications include cable harness testing, semiconductor and PCB testing, and applications where multiple points need to be switched to a common resource. The EX1200-3001 and EX1200-3001DS consist of eight individual (1 x 8) 2-wire multiplexers, or eight (1 x 16) 1-wire multiplexers that can be interconnected under program control (via the bussing relays) to configure larger multiplexers as required. This eliminates external wiring and helps reduce unterminated stubs. The card has internal relays that can be closed to connect directly to the EX1200 analog bus. This feature allows the card and the internal EX1200 DMM to be tightly coupled, dramatically reducing test execution times. The EX1200-3001DS option includes internal residual voltage discharge relays can be enabled to momentarily short out the measurement path when changing from one input channel to the next. This dissipates any voltage held by the wiring and instrument input capacitance. These relays protect sensitive devices, such as CMOS circuits, from residual voltages caused by previous high-voltage measurements.

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.
