z CT Inputs
Models with an option number of 001 to 003, 008 to 012, 017, or 023 have one or more CT inputs.
Note: The E5CC-U does not have CT inputs.
z Transfer Output
Models with an option number of 006 or 011 to 014 have a transfer output.
E5CC
E5EC/E5AC
Note: The E5CC-U, E5DC, and E5GC do not have a transfer output. However, if the control output is a linear
current output for the E5CC-U* or E5GC, the control output can be used as a simple transfer output. For
details on the operating procedure, refer to 5-13 Using the Transfer Output.
*The Digital Controller must be manufactured in May 2014 or later (version 2.2 or higher).
z Remote SP Input
Models with an option number of 007 or 011 to 014 have a remote SP input.
Note: The E5CC-U, E5DC, and E5GC do not have a remote SP input.
The remote SP input circuit is not electrically isolated from the internal circuits. Therefore, when using a
grounded sensor input, do not connect the remote SP input terminals to ground. (If the remote SP input
terminals are connected to ground, errors will occur in the measured temperature as a result of leakage
current.)
z Potentiometer Input
You can use this input for a Position-proportional Model. The maximum opening can be measured to between
100 and 10KΩ.
Note: The E5CC, E5CC-U, E5DC, and E5GC do not have a potentiometer input.
