ABB DSAO120A 3BSE018293R1｜Analog Output Board｜
DSAO120A 3BSE018293R1
16 channel analog output
Each card provides 16 independent analog outputs, standard industrial signal 4-20mA, to drive on-site actuators such as regulating valves, positioners, and frequency converters.
Channel isolation design
Each channel is equipped with electrical isolation to suppress ground loop interference, and a single on-site short circuit will not damage the entire card.
High precision control output
High resolution, suitable for closed-loop regulation of processes (temperature, pressure, flow, and liquid level control circuits), meeting continuous process control needs in power plants, chemical industries, papermaking, and other industries.
Hardware fault self diagnosis
Real time detection of wire breakage, load short circuit, and output overload, with fault information uploaded to the controller for easy and rapid maintenance.
Hot swappable support
The rack can be replaced separately when it is electrified, without interrupting other control circuits of the entire cabinet, ensuring the continuous operation of the device.
Backplane bus communication
Cooperate with DSBB110A backplane bus module to exchange high-speed data with AC410/AC450 main control.
