-2LC, the rated temperature range, digital output value, and resolution depend on the selected sensor
and mode.
*2.
Accuracy is not guaranteed for the temperature range of 0
°C to 399°C(0°F to 799°F) of the thermocouple -B input
and for the temperature range of 0°F to 32°F of the PL II and WRe5-26 inputs.

Input characteristics
Insulation method
• The photocoupler is used to insulate the analog input area from the PLC.
• The DC/DC converter is used to insulate the power supply from the analog inputs.
• Channels are insulated from each other.
• The DC/DC converter is used to insulate the power supply from the analog inputs.
• Channels are insulated from each other.
