Wiring Terminals Section 2-2
CT Inputs When the HB alarm, HS alarm, or heater overcurrent alarm is to be used
with the E5CN-H@M@-500 with an E53-CN@H/HH@N2 Option Unit, connect
a current transformer (CT) across terminals 14 and 15 or terminals
13 and 15 (no polarity).
When the HB alarm, HS alarm, or heater overcurrent alarm is to be used
with the E5AN/EN-H@@H@-500 or E5AN/EN-H@@HH@-500, connect a
current transformer (CT) across terminals 14 and 15 or terminals 15 and
16 (no polarity).

Transfer Output On the E5CN-H@M@-500 with an E53-CN@FN2, the transfer output is
output across terminals 14 and 15.
On the E5AN/EN-H@@F-500, transfer output is output across terminals
27 and 28.

Even with models that do not have a transfer output, control outputs 1 or 2 can
be used as a simple transfer output if it is a current output or linear output. For
details on the operation, refer to 4-14 Using the Transfer Output.
Remote SP Input The E5AN-H and E5EN-H support remote SP inputs. To use remote SP,
connect to terminals 29 and 30.
CT2
Remote SP inputs are not electrically isolated from the internal circuits. When
using a grounding thermocouple, do not connect any of the remote SP input
terminals to the ground. (If a remote SP input terminal is connected to the
ground, errors will occur in the measured temperature as a result of leakage
current.)
