Description
The High-Voltage Terminal Block, with part number 777687-25, falls under the category of SCXI & Legacy and is designated as model SCXI-1325. This terminal block is specifically designed for high-voltage applications, providing a reliable solution for signal connections and chassis ground requirements.
It features 26 screw terminals, which include 2 terminals dedicated for SCXI-1124 chassis ground and 24 terminals for signal connections. This terminal block is compatible exclusively with the SCXI-1124 Analog Output Module, ensuring seamless integration for users of this particular module.
For installation, the terminal block is mounted on the front panel of the host module through mating connectors, offering a straightforward and secure connection. It boasts an isolation capacity of 250 Vrms both channel to ground and channel to channel, with a DC rejection capacity of ±50 VDC in 1 MΩ common mode. Additionally, the terminal block features an RC corner frequency of 0.16 Hz 1-pole and can handle a common mode voltage (CMV) of up to 250 Vrms.
Constructed with isothermal materials for durability and performance, the terminal block accommodates a field wire gauge range of 26-14 AWG maximum. It is rated for 250 V, CAT II, ensuring it meets various application requirements securely. The terminal block operates efficiently within a temperature range of 0 to 50 °C and can be stored in temperatures ranging from –20 to 70 °C. Its relative humidity tolerance is 5% to 90% (non-condensing), making it suitable for a wide range of environmental conditions.
The terminal block adheres to several electrical safety standards, including IEC 61010-1, UL 3111-1, and CAN/CSA C22.2 No. 1010.1, ensuring it meets the highest safety and quality standards. Although declared obsolete by National Instruments, it remains available through Apex Waves, providing users with continued access to essential high
