MPN: 1746-NO4I — industrial control spare part, in stock at TGK Parts.
The 1746-NO4I is the 4-channel current analog output module of the SLC 500 1746-NO4 family, driving valve positioners, VFD speed references and analog meters. Analog modules age harder than digital ones — calibration drift and DAC failures are common after 15+ years in service, and used units are only worth buying with a calibration report.
Every 1746-NO4I we ship is verified on all four channels with measured output current and linearity check.

Replacement and spare part for industrial automation equipment — production lines, CNC machines, packaging machinery, textile machinery, printing equipment and more.
Not directly — use the -NO4V voltage variant or add a 250 ohm converting resistor at the drive input.
Each channel is driven at 0/25/50/75/100% and output current is measured; the report ships with the module.
No — current and voltage output stages differ; match the module to your loop wiring.
