| AS0 SERIES Current Operated Switches |
| |
| AS0 Series Low-current Sensors are specialized current operated switches that combine an ultra-sensitive current transformer and signal conditioning electronics into a single package for sensing AC current from 3–350mA. Useful for signal or lamp status monitoring, detecting minute fault currents or fan proving, the AS0 Series features solid-state outputs and jumper-selectable ranges, which make it a versatile choice for low-current status indication applications. |

Fan Monitoring
- Fan status in heating and drying
applications.
- Identify lamp outages or other malfunctions
through changes in current consumption.
|
Fractional HP Motors
Ideal for monitoring small motors used in critical applications, for example, fan-proving on a crucial cooling fan. |
Fault Current Sensing
Detects extremely low levels of current resulting from fault conditions. |
|
- Wide Range of Output Options:
- Dependable, solid state switch N.O. or
N.C. contacts rated at 240VAC or 30VDC.
- Compatible with most automation
controllers.
- Isolated Inputs and Outputs:
- Inductive sensing eliminates insertion
loads on monitored circuits, effectively isolating it from the unit.
- Isolated outputs simplify wiring and
enhance safety.
- Adjustable Setpoints - Setpoints are field adjustable from 3mA to 350mA, speeding installation and allowing for tailored applications.
- UL, CUL and CE Approval - Accepted worldwide.
