National Instruments TB-2666 Terminal Block

The TB-2666 (Part Number: 778717-66) from National Instruments is a front-mounting, industrial PXI Terminal Block that is specifically designed to be used in conjunction with the PXIe-2566 PXI Relay Module. The TB-2666 is designed with screw terminals for convenient access to its 16 relays. This ensures users can easily connect and control the device's operations. Moreover, the terminal block provides connections for input and output trigger signals, making it a crucial part of any PXIe-2566 configuration. The TB-2666 is designed to provide maximum signal voltage range of 150 V as well as an impressive capability of withstanding impulse voltage up to 800 V. With these features, the TB-2666 is built to handle some of the toughest industrial environments.

National Instruments Terminal Blocks are manufactured for superior quality and durability, and they can be utilized with shielded cables to achieve a durable signal termination with minimal noise. Even in some of the most challenging industrial environments, terminal blocks allows your signals to remain clear and accurate.

The TB-2666 Terminal Block is the ideal match for the PXI‑2566 - a switch module with individual single-pole double-throw (SPDT) Form C armature relays. It is specifically engineered for this purpose. Each relay of the PXI-2566 is nonlatching, and has very low on-resistance and thermal offsets. This module is very useful and convenient to use, as it comes with a NC, NO, and COM terminal in every relay channel. This makes it incredibly versatile so that you can use it for different purposes. The PXI-2566 Relay Module is the perfect choice for switching, routing, and controlling high-current signals due to its reliable performance.

When used in conjunction with the TB-2666, the DC isolation of the PXIe-2566 is an impressive 100 GΩ, which is typical for both open channel and channel-to-channel configurations. In addition, the bandwidth of the PXIe-2566 in this state is typically ≥10 MHz, making it a reliable choice for a wide range of applications.
