STB AVI 1270 Physical Description
Physical
Characteristics
The STB AVI 1270 is a standard Advantys STB two-channel analog input module
that reads inputs from analog sensors that operate over the range -10 to +10 V. 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.
