Product overview

The module, when installed in an sc200 or a Polymetron 9500 controller, allows an analog sensor to
connect to the controller.
Installation
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the document.
Measurement variations of approximately 8% occur at ~25 MHz and in the 600-700 MHz frequency band. These
deviations occur only with 1 kHz 80% carrier amplitude modulation, and although amplitude modulated signals in
this band are unlikely to occur at customer installations, user care in the routing of both probe cable and controller
power lines to avoid ambient field interference is necessary.
Connect the sensor to the module
Potential electrocution hazard. Always disconnect power to the controller when making electrical connections.
