The National Instruments BNC-2115 (Part Number: 777807-01) is a shielded connector block compatible with E Series devices. This robust accessory facilitates seamless I/O signal connectivity through its 24 BNC connectors and a two-position screw terminal, enabling efficient connection of digital input/output signals to devices such as the PCI-6033E, PCI/PXI-6025E, PCI/PXI-6031E, PCI/PXI-6071E, AT-MIO-16DE-10, and AT-MIO-64E-3. The BNC-2115 supports the operation of digital signals and can be configured to increase the analog channel count by utilizing either non-referenced or referenced single-ended modes, allowing two single-ended channels per BNC coaxial cable. The block is designed to operate safely with voltages up to 42 V, beyond which, damage may occur to the connector, host computer, or connected devices.

This connector block, equipped with a 68-pin male I/O connector on the rear panel, is capable of linking extended digital I/O and extended analog inputs of 64-channel multifunction DAQ devices. It requires the SH1006868 cable for operation. Designed for versatility, the BNC-2115 can be mounted on a DIN rail or used in desktop configurations, although mounting accessories must be purchased separately. The block is fully programmable using software such as NIDAQmx driver software, LabVIEW, or LabWindows/CVI.

Measuring 7.5 x 4.125 x 1.38 inches, the BNC-2115 operates within a temperature range of 0 to 70 °C and offers a storage temperature range of -55 to 125 °C, with a relative humidity tolerance of 5 to 90% non-condensing. The connector block adheres to several electrical safety standards, including IEC 61010-1, EN 61010-1, UL 3111-1, UL 61010B-1, and CAN/CSA C22.2 No. 1010.1.
