NI TB-2630B Front-Mounting Terminal Block

The NI TB-2630B is a front-mounting terminal block designed to configure the NI PXI-2530B switch module as a multiplexer across multiple channel architectures. This shielded accessory connects directly to the PXI-2530B front panel I/O through ribbon cable headers and provides screw terminals for trigger input and output signals. Installation is straightforward, positioning the terminal block in front of the switch module to enable signal routing and multiplexer configuration.

– Key Features

Connectivity: Ribbon cable headers (2×9 pin connectors) route signals to the switch module. Screw terminals accommodate trigger input and trigger output signals independently.

Shielding: Fully shielded construction ensures compliance with EMF specifications and stable operation in high electrical noise environments.

Safety & Compliance: Meets IEC 61010-1, EN 61010-1, UL 61010-1, and CSA 61010-1. Electromagnetic compatibility certified to EN 61326-1 (Class A emissions, basic immunity), EN 55011 (CISPR 11, Group 1, Class A), AS/NZS CISPR 11 (Group 1, Class A), FCC 47 CFR Part 15B (Class A), and ICES-001 (Class A). CE marked for Low-Voltage and EMC Directives.

– Typical Applications

Multiplexed switching across precision measurement, test automation, and data acquisition systems requiring flexible channel configurations and external trigger synchronization.

– Compatibility & Integration

Front-mounting design integrates with the NI PXI-2530B switch module only. Antistatic handling precautions and grounding procedures apply during installation.
