It receives 4-20mA and 0-10V analog signals from field sensors and transmitters, converts analog signals to digital values for controller processing. It adopts multi-channel design with galvanic isolation and built-in hardware fault diagnosis. Widely used in power, pulp & paper and chemical industrial process control.

Content Details

DSAI133A is a rack plug-in S100 I/O module for Advant OCS control rack. It transmits converted digital data to the main CPU via ModuleBus backplane. Channel isolation effectively blocks field surge interference and improves system stability. Onboard diagnostics detect open circuit, signal abnormality and module failure, uploading alarm data to DCS. LED status indicators facilitate quick status check and fault location on site. Rugged industrial PCB maintains reliable operation under vibration and strong electromagnetic interference. It is used as spare part replacement and system upgrade component for Advant OCS DCS. Each module completes full function test and thermal aging test before delivery.
