Chapter 1 - Overview

The 9125 is SSi’s versatile atmosphere controller with Ethernet, RS485 Modbus, and DF1 communications to various client devices such as temperature controllers, flow meters, and PLCs.  This instrument can be used to address many thermal processing applications where temperature and carbon control along with event I/O management are necessary.  The 9125 has math block capability allowing custom calculations and custom Modbus mapping for communications.

 

The 9125 also supports multiple user interface screens for more flexibility. Screen sizes include 3.5”, 5.7” and 12.1”. Functionality added to the screens include “stylus” notes entry, user defined data points and trend charts for paperless chart recording, zoom and pan touch screen control on the charting screen, and remote data retrieval through Ethernet.
