Sensor Input
 Model Numbers
All E5CD models have universal sensor inputs, so the code in the model number is always "M."

Precautions for Correct Use
• When complying with EMC standards, the line connecting the sensor must be 30 m or less. If
the cable length exceeds 30 m, compliance with EMC standards will not be possible.
• The sensor input is not electrically isolated from the internal circuits. If you use a grounded
thermocouple, do not connect one of the sensor input terminals to ground. (If the sensor input
terminals are connected to ground, errors will occur in the measured temperature as a result
of leakage current.)
