STB ACI 1225 Physical Description
Physical
Characteristics
The STB ACI 1225 is a basic Advantys STB single-ended two-channel analog
current input module that reads inputs from analog sensors that operate over the
range 4 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.
