SCXI-1127 High voltage matrix/multiplexer module

This SCXI-1127(part number :776572-27) is a high voltage matrix/multiplexer module available in a variety of configurations :1 x 32, two-line multiplexer, two 1 x 16 two-line multiplexers, and one 4-line 1 x 8 multiplexer. For special terminal boards, there may be more configurations, such as 4 x 8,2 wire or 1 x 32,2 wire matrix. The module can also be used as a 1 x 64, 1-wire or 1 x 64, 4-wire multiplexer by using software-configurable switches. This nickel SCXI-1127 is ideal for low and high voltages. For low voltage measurements, the matrix/multiplexer switch module utilizes an extremely low thermal offset relay to ensure accurate measurements. For high voltage measurements, on the other hand, the module can withstand signals of 250 Vrms at 200 mA loads and 30 VDC at 1 A loads. NI instruments are equipped with 64 channels with a maximum bandwidth of 11 MHz.

This SCXI 1127 operates using NI-SWITCH driver software that supports application development environments (ADE), such as LabVIEW, Measurement Studio, Visual Basic, Microsoft C, and C++. The device can be configured using measurement and automated browser tools.

This nickel SCXI-1127 has a multifunctional scanning structure. Users can scan the channels arbitrarily, and there are multiple input modes in a single scan, which helps connect multiple types of sensors to a single module. The SCXI-1127 has two scanning methods: software scanning and hardware timing scanning. Software scan allows channels to be selected through software. This process does not need to trigger a connection. In addition, software scans do not provide the time accuracy that hardware timing scans provide. Hardware timing scanning enables measuring devices such as DMM to communicate with nickel SCXI-1127 through digital trigger signals. There are also two types of hardware timing scans: synchronous scanning and handshake. A synchronous scan requires only a single signal from the device to the multiplexer, but a handshake requires another signal from the multiplexer linked to the device. The SCXI-1127 weighs 1 lb and measures 1.2 x 6.8 x 7.8 inches.
