Product Details

57310255‑AV,type DSAO120,is S100 series 8‑channel analog output module for ABB Advant Master DCS system.

It converts internal controller digital values into 4‑20mA / 0‑10V analog signals and outputs to field actuators. Each channel has LED status indicator for on‑site troubleshooting. Channel‑to‑bus isolation improves anti‑interference performance,with short‑circuit protection function. Module fault will cause partial or all analog output loss,loop control failure. Widely used for old‑generation S100 I/O site maintenance.

Note:This is legacy EOL spare component,widely used for process industry spare‑part replacement.
