NI SCXI-1124 6-Channel Isolated Analog Output Module

The NI SCXI-1124 is a 6-channel isolated analog output module built for the SCXI signal conditioning platform. Each independent channel can be configured for voltage or current output, with 250 Vrms isolation to separate the control system from field actuators and avoid ground loop interference.

This discontinued legacy DAQ module requires a compatible SCXI chassis and NI DAQ hardware. It is widely used as spare replacement for process control systems, test benches and automation equipment built on older NI measurement platforms.
