CAUTION
Inputs to the current input terminals 31 and 33 on the DCP31 should be within the
current range listed in the specifications.
Failure to do so might cause fire or faulty operation.
The maximum input ratings are as follows:
Thermocouple and DC voltage inputs: -5 to +15 V dc
DC current input: 50 mA dc at 2.5 V dc
Handling Precautions
• Applying voltage across dc current input terminals ( ) and ( )
may cause faulty operation.
• Take care of polarities (+, −) when wiring inputs.
• Use only shielded cable for wiring inputs.
• When using a thermocouple input, prevent air blasts from
coming into contact with the terminal. Doing so might cause a
reading error.
