4-2 Compensating Lead

In the case of thermocouple input, connect the bare thermocouple lead to the terminal. If the thermocouple is located a long way from the DCP301 or the thermocouple is connected to a terminal, extend the connection using a compen- sating lead and then connect to the terminal. Use shielded compensating leads only.

For I/O other than thermocouples, use JCS-364 shielded instrument polyethylene insu- lated vinyl sheath cable or equivalent product. (This is generally referred to “twisted shielded cable for instruments.”) The following cables are recommended.
