The 1794-IT8 is compatible with any available Flex I/O communication adapter. This module is a compatible on being operated in Temperature application ranges such as 300 to 1800oC (572 to 3272oF) using Type B Thermocouple; 0 to 2315oC (32 to 4199oF) Type C; –230 to 1000oC (–382 to 1832oF) Type E; –195 to 1200oC (–319 to 2192oF) Type J; –230 to 1372oC (–382 to 2502oF) type K; –270 to 1300oC (–450 to 2372oF) Type N; –50 to 1768oC (–58 to 3214oF) Type R; –50 to 1768oC (–58 to 3214oF) Type S; –195 to 400oC (–319 to 752oF) type T; –175 to 800oC (–283 to 1472oF) type L. Milivolt input signals are practically used with transducers and other instruments that produce non-standard signals. Data exchange with the 1794-IT8 Thermocouple input module is configured using the block transfer operation.
Before inserting the 1794-IT8 module on the terminal base, the users should rotate the key switch on the base to Position 3 because this position is required for the safe mounting and operation of the thermocouple/mV module. The 1794-IT8 FLEX I/O thermocouple module communicates with PLCs through the block-transferring option. Block transfer programming relies on input signal data words moving between the thermocouple module’s memory and a designated area in the PLC’s data table.
