The HE693THM884M allows thermocouple temperature sensors to be connected to the PLC directly without the use of 

external signal processing such as transducers, transmitters, etc. All analog and digital processing of the thermocouple 

signal is performed on the module. This high-resolution module (0.1°C), can report values to the PLC I/O table in 0.5°C,

0.5°F, 0.1°C, or 0.1°F increments. The module has eight thermocouple channels assigned to 8 %AI input registers. There 

are 16 %I Alarm Bits, one open circuit alarm and one setpoint alarm for each channel. Alarm setpoints are set for 

each channel through 8 %AQ registers. Open circuit alarm bits for each channel correspond to the first eight successive%

I bits, and the alarm setpoints for each channel correspond to the second eight successive %I bits.
