TEMPERATURE CONTROLLER E5EX–H
DIN-sized (96 x 48-mm) Temperature
Controller Featuring Advanced PID
Control and Heater Burnout Detection
Advanced
PID control with two
degrees of freedom
improves stability and response speed.
Heater burnout alarm built in.
Select
from seven temperature sensors and a total
of 14 temperature ranges (seven Fahrenheit and
seven Celsius).
High accuracy: 0.3% of set value.
Ordering Information

to
specify an Control Output Unit and Current T
Example: E5EX–AH, Relay Output Unit E53–R, Current T
Models set to display in degrees Fahrenheit (°F) can be ordered by adding “–F” to the end of the model number
The scale indication switch will then be set to °F prior to shipment from the factory
