National Instruments 780587-27 Multiplexer Switch Module 

National Instruments part number 780587-27 is an identifying part number for the PXIe-2527, a PXI Multiplexer Switch Module. This module includes 32 channels and a maximum switching voltage of 300 Volts. This high-voltage PXI multiplexer switch module is designed for medium- to high-density automated test applications. 

Equipped with high-power electromechanical relays, it serves as an ideal front end for PXI DMM modules, enabling straightforward channel expansion for diverse measurements. The module supports various channel configurations, including 64x1 1-wire, 32x1 2-wire, and 16x1 4-wire setups. Additionally, it includes onboard relay counting for monitoring and ensures deterministic operation with hardware triggers to enhance test throughput. This module can handle switching voltages of up to 300 V, with a maximum switching or carry current of 2A. It can accommodate switch loads with a minimum voltage of 20 mV and a minimum current of 1 mA. 

The part number 780587-01 comes with multiple I/O connectors including a 100-position HDI right-angle male connector. For user convenience, it offers a range of accessories including NI terminal blocks, a relay replacement kit, and various connectors. It meets stringent electromagnetic compatibility standards and operates with the NI-SWITCH driver software for seamless integration and control.

The module includes transient suppression functionality to enhance the longevity of the NI 780587-01. The module helps with thermocouple measurements using NI software. It also has different I/O connectors, like a 100-position HDI right-angle male connector. Additionally, it has impressive trigger capabilities, utilizing PXI trigger lines 0 to 7 as input triggers with a minimum pulse width of 150 nanoseconds. The output pulse trigger is programmable within a range of 1 microsecond to 62 microseconds. For power requirements, the device consumes 7.5 W at 12 V and 2.5 W at 3.3 V.
