The Model SSI is an indication system consisting of 2 separate parts, a Controller-Display module and one or more Field Modules. Together, this system provides an indication which field device has been actuated and allows the operator to concentrate his efforts on one particular unit or location. The Field Module can be installed in any device with a spare N/C (normally closed) contact.

The Status System Indicator provides indication on larger overland conveyor systems which switch or control has been actuated, saving time searching the many units on site.
