Description
The 188835C-01L, also known by its alternate part number 778717-66, is categorized under PXI Switches and is specifically the model TB-2666. This piece of equipment is a terminal block designed for the NI PXI-2566, making it compatible with the PXIe-2566 PXI Relay Module. Its installation is facilitated through front-mounting, which allows for easy setup and access.
The terminal block features screw terminals for 16 relays, ensuring a secure and reliable connection for each relay in the system. It also supports input/output trigger signals, enhancing its functionality and versatility in various applications. The maximum signal voltage it can handle is 150 V, and it has an impressive impulse voltage withstand of 800 V, ensuring its durability and reliability in demanding environments.
Each relay within this terminal block is a Single-pole double-throw (SPDT) Form C armature relay, known for their nonlatching nature, low on-resistance, and minimal thermal offsets. These features make them ideal for a wide range of applications. Additionally, each relay has terminals for NC, NO, COM (Normally Closed, Normally Open, Common), providing flexibility in how they are integrated into circuits.
The terminal block boasts a high DC isolation rate of 100 GΩ, ensuring minimal interference and maximum signal integrity. Its bandwidth is rated at ≥10 MHz, which is sufficient for a wide range of applications, from automation to testing environments. This combination of features makes the TB-2666 an essential component for professionals working with PXI Relay Modules, offering reliability, flexibility, and performance.
