This unit
The DGH D4262 is a computer-to-analog output module that translates ASCII serial commands into configurable voltage or current signals for external system control. Operating over RS-232 or RS-485 serial interfaces at rates from 300 to 38,400 baud, it bridges host computers and industrial/laboratory equipment with 12-bit resolution and 500Vrms output isolation. The module accepts +10 to +30VDC unregulated power and delivers precision analog outputs across eight selectable ranges: 0–1V, ±1V, 0–5V, ±5V, 0–10V, ±10V, 0–20mA, and 4–20mA.
