The National Instruments SCXI-1325 is a shielded connector block engineered for direct integration with the SCXI-1124 analog output module. It provides signal conditioning and field wiring termination through 26 screw terminals, with isothermal construction designed for high-accuracy measurement in industrial test environments. The unit handles both analog and digital I/O connectivity while maintaining channel-to-ground and channel-to-channel isolation at 250 Vrms.
