Physical
Characteristics
The STB ACI 1230 is a standard Advantys STB analog current input module with
two single-ended analog channels that read inputs from analog sensors operating
in the range 0 to 20 mA. The analog portion of the module is isolated from the
island’s sensor bus to improve performance. To take advantage of this internal
isolation feature, the sensors must be powered from an external power supply. If
isolation is not required, you can use the module to deliver field power to the
sensors—24 VDC for sensor 1 from the top connector, and 24 VDC for sensor 2
from the bottom connector. The module mounts in a size 1 I/O base and uses two
six-terminal field wiring connectors.
