The HE693THM166 offers exceptional channel density, with 16 input channels per module. This module permits thermocouple temperature sensors to be directly connected to the PLC without external signal processing (transducers, transmitters, etc.). All analog and digital processing of the thermocouple signal is performed on the module. Temperature resolution is 0.5°C, and temperature values may be reported to the PLC %AI I/O table in 0.5°C or 0.5°F increments. This module features open circuit detection, where the %AI register goes to its maximum value upon an open circuit condition, and a corresponding %I bit is energized. Field wiring is connected to a special high density, 32 positions removable terminal block.
