TB-2643B

Description

The NI TB-2643B Terminal Block is an accessory designed to facilitate cable-less deployment in configurations such as a 2-wire, 4 x 64 matrix or a single-wire, dual 4 x 64 matrix, exclusively compatible with the NI-2532B Switch Module. Its design boasts an optional provision for protection resistance, enhancing the safety and integrity of connections.

It encompasses a variety of part numbers including 153631-01L, 153631-02L, 782385-07, and 782385-08, with the latter two distinguishing between models with and without protection resistance, respectively. The shielded design of this terminal block ensures robust operation, and its rear connection seamlessly mates with the front connectors of either the PXI-2532B or PXIe-2532B Switch Modules.

Intended for use in Measurement Category I environments, the TB-2643B can handle signals up to 100 volts and is tested to withstand surge voltages up to 500 V. The optional 100 Ω column and row protection resistors provide an additional layer of defense against current overloads, illustrating the terminal block’s commitment to reliability and safety in electrical measurements.

Question 1: What distinguishes the 782385-07 and 782385-08 part numbers in the NI TB-2643B Terminal Block series, and how do these models relate to the inclusion of protection resistance?
Answer 1: The NI TB-2643B Terminal Block model 782385-07 includes 100 Ω column and row protection resistors, whereas model 782385-08 does not have these protection resistors.

Question 2: What are the key features and part numbers of the NI TB-2643B Terminal Block, and how do these relate to its compatibility and safety when used with NI-2532B Switch Modules?
Answer 2: The NI TB-2643B Terminal Block is designed for cable-less deployment in configurations such as a 2-wire, 4 x 64 matrix or a single-wire, dual 4 x 64 matrix, and is exclusively compatible with the NI-2532B Switch Module; it features optional 100 Ω protection resistors for safety, supports Measurement Category I environments, handles up to 100 volts, and is shielded for robust operation, with part numbers distinguishing between models with

Question 3: What distinguishes the NI TB-2643B Terminal Block models 782385-07 and 782385-08 from each other?
Answer 3: The NI TB-2643B Terminal Block, designed for cable-less deployment with the NI-2532B Switch Module, features part numbers 153631-01L, 153631-02L for standard models and 782385-07, 782385-08 for models with and without optional 100 Ω protection resistors, respectively. These protection resistors, along with the shielded design and rear connection, enhance safety and reliability by providing surge protection up to 500 V

Question 4: What are the distinguishing features and intended usage conditions of the NI TB-2643B Terminal Block in relation to its compatibility with the NI-2532B Switch Module?
Answer 4: The NI TB-2643B Terminal Block is designed for cable-less deployment compatible with NI-2532B Switch Modules, offering configurations such as a 2-wire, 4 x 64 matrix or a single-wire, dual 4 x 64 matrix, and includes part numbers 153631-01L, 153631-02L, 782385-07, and 782385-08, with the last two indicating the presence or absence of optional protection resistance.

Question 5: What are the distinguishing features and part numbers of the NI TB-2643B Terminal Block when deployed with the NI-2532B Switch Module, and how do they contribute to safety and reliability in Measurement Category I environments?
Answer 5: The 782385-07 and 782385-08 part numbers in the NI TB-2643B Terminal Block series distinguish between models with 100 Ω column and row protection resistors (782385-07) and those without protection resistors (782385-08), relating directly to the inclusion or exclusion of this additional safety feature.
