Functional Features

• 16-Channel High-Density Design: Offers superior channel density with 16 thermocouple inputs per module, increasing system integration and saving panel space .

• Direct PLC Integration: Allows thermocouple sensors to connect directly to the Series 90-30 PLC backplane, eliminating the need for external transmitters or signal conditioners .

• Open Circuit Detection: Built-in diagnostic feature where the %AI register goes to its maximum value upon an open circuit condition, and a corresponding %I bit is energized for immediate fault identification .

• Configurable Temperature Units: Temperature values can be reported in 0.5°C or 0.5°F increments, selectable through configuration parameters for application flexibility .

• Wide Thermocouple Compatibility: Supports 10 thermocouple types (J, K, N, T, E, R, S, B, C, X), covering measurement ranges from cryogenic to extremely high-temperature applications .

• Superior Noise Rejection: Common mode rejection exceeding 100dB and 20 Megohm input impedance ensure stable readings in electrically noisy industrial environments .

• Removable Terminal Block: Uses a special 32-position high-density removable terminal block for convenient field wiring and maintenance .
