AMETEK Scientific Columbus 6271A-150VDC DC Isolation Amplifier

The AMETEK Scientific Columbus 6271A-150VDC is a DC voltage isolation amplifier that provides galvanic isolation between a low-level input signal and an isolated output, enabling safe signal transfer from sensors to control electronics in rugged environments. In standard configurations, it accepts a small DC input (commonly 0–100 mV DC) and yields an isolated output in the 0–10 V DC range, with P-Option calibrations for 5, 20, or 50 mA depending on the selected output range. The device is designed for high reliability, featuring a dielectric withstand of 1500 Vrms at 60 Hz between input and output/power/case. Power is supplied from an external auxiliary source (108–132 VAC, 50/60 Hz) as used in the 6271A family, and typical accuracy is ±0.5% RO at 25°C with ±0.7% of span and a temperature coefficient around ±0.04%/°C.
