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.
Connect the sensor to the module
Potential electrocution hazard. Always disconnect power to the controller when making electrical connections.
Electrocution hazard. High voltage wiring for the controller is conducted behind the high voltage barrier in the
controller enclosure. The barrier must remain in place except when installing modules, or when a qualified
installation technician is wiring for power, relays or analog and network cards.
Potential instrument damage. Delicate internal electronic components can be damaged by static electricity,
resulting in degraded performance or eventual failure.
To install the module and connect the sensor, refer to the wiring tables and the illustrated steps that
follow.
Be sure to connect all sensor ground/shield wires to the controller enclosure grounding screws.
