Omron E5AN - Wiring Terminals

Wiring Terminals Section 2-2
Do not connect a different type of terminal block to a Controller. For example,
do not replace a screw terminal block with a screwless clamp terminal block.
The temperature indication accuracy will decrease.
2-2 Wiring Terminals
Confirm the location of the terminals (terminals 1 to 15 for the E5CN, 1 to 30
for the E5AN and E5EN, and terminals 1 to 14 for the E5GN) using the prod-
uct labels and case markings.

Option Units
Since the voltage output (control output) is not electrically insulated from the internal wiring, one or other of
the control output terminals must be left unearthed when using an earthed thermocouple thermometer. (Con-
nection makes measurements unreliable due to sneak currents.)
To comply with EMC standards, the length of the cable connecting the analog input or universal TC/Pt input
sensor must be 30 m or less. If the cable is longer than 30 m, the EMC standards will not be satisfied.

A heater burnout alarm, heater short alarm,
heater overcurrent alarm, or input error is
sent to the output to which the alarm 1
function is assigned.
The E5@N-@@@T@ is set for a K thermocouple
(input type of 5) by default. If a difference sensor is
used, an input error (s.err) will occur. Check the
setting of the input type parameter.
