Description
The High-Voltage Terminal Block with part number 777687-25 is categorized under SCXI & Legacy. Specifically, this model, SCXI-1325, is designed to provide efficient and reliable connections for high-voltage applications.
It features 26 screw terminals and is compatible with the SCXI-1124 Analog Output Module. The terminal block mounts easily on the front panel of the host module through mating connectors, ensuring a secure and stable connection.
This terminal block offers excellent isolation capabilities, with 250 Vrms channel to ground and channel to channel, and it has a DC rejection capacity of ±50 VDC. The RC corner frequency is specified at 0.16 Hz 1-pole, with a common mode voltage (CMV) of up to 250 Vrms.
Constructed isothermally, it supports field wire gauges ranging from 26-14 AWG and has a device rating of 250 V, CAT II. The terminal block is built to operate within a temperature range of 0 to 50 °C and can be stored in temperatures ranging from -20 to 70 °C. It also operates reliably within a relative humidity range of 5% to 90% (non-condensing).
Compliance with electrical safety standards is paramount, and this terminal block meets IEC 61010-1, UL 3111-1, and CAN/CSA C22.2 No. 1010.1 standards. Despite being declared obsolete by National Instruments, it remains available for purchase and repairs through Apex Waves, ensuring continued support for users who rely on this high-voltage terminal block for their applications.
