The EX1200-2087A is a high voltage multiplexer module with built in self-monitoring capability which allows each relay to be monitored continuously and prevents unintentional routing of high voltage signals to/from the UUT. The EX1200-2087A self-monitoring mechanism continuously monitors the relays to ensure that contacts haven’t been welded shut and the unit under test isn’t exposed to unintended connection paths. When failures are detected, interrupts can be generated that immediately stop the test. It is the first relay board in its class to offer this level of assurance and protection and is ideal for safety critical applications where cost of failure can be high, for example to test power distribution systems, electrical safety testing, and insulation testing. The EX1200-2087A has been designed to switch voltages up to 1000V at power levels up to 25 VA. Each card contains eight banks of 1x2, 2 wire multiplexers.

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. 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 (1x24) 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.

The EX1200-3048S is a high-density FET multiplexer module designed for scanning of multiple points to a common bus in either 2- or 4-wire configurations. The solid-state design delivers maximum switching speed and near infinite life. 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. Typical applications include temperature and voltage data acquisition and datalogging at up to 1000 scans per second. The EX1200-3048S consists of dual (1x24) 2-wire multiplexer banks. Each bank can be interconnected within a module under program control (via bussing relays) and across modules via the EX1200 analog bus to configure larger multiplexers as required. This eliminates external wiring and helps reduce unterminated stubs. 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.

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.

The EX1200-3164 high-density multiplexer module is designed to provide a flexible switching multiplexing architecture with 16 individual 1x4 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 1x64. 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.

The EX1200-3824 is a high speed multiplexer designed to provide flexible switching multiplexing architecture with 8 banks of 1 x 24 one-wire multiplexers. Up to 48 1 x 24 one-wire channels can be accommodated in a 1U EX1200 full rack mainframe for maximum density, or mixed and matched with other EX1200 plug-ins for flexibility. The solid-state design delivers extremely fast switching speed and near infinite life. The EX1200-3824 may be used in applications in which its inputs are connected to DUT capable of producing signals that approach 100 V, with its commons being connected to high-speed measurement devices. When measurement devices are limited to 10 V input ranges, the EX1200-3824 offers the option of an on-board 10:1 attenuator to eliminate the need for external circuitry while ensuring maximum signal integrity. The EX1200-3824 can be controlled programmatically using IviSwtch-compliant calls. Both path level programming and individual relay control are available to simplify integration into test systems. On-board configuration relays are available to connect the individual banks together, providing the system designer with the flexbility to create test programs utilizing discrete 1 x 24s or configurations as large as 1 x 192 without external wiring.
