TTSI

As the name describes, the TTSI is the interface between the sensor and the customer equipment.  On the customer side, the TTSI can provide operator displays, analog I/O, digital communications, and/or discrete digital I/O that are compatible with customer equipment.  The TTSI can be provided in a self-contained enclosure, or as DIN rail mountable components that can be added to existing control cabinets.  The purpose of the TTSI is to provide a low-cost interface between the sensor and the customer equipment.

The main components of the TTSI are a PLC and Operator Display.
