E5AR Digital Controllers offer high speed,
high precision, and multiple I/O and use a 5-digit,
3-row LCD display for high visual clarity.
A short sampling period of 50 ms enables use in applications,
requiring high-speed response.
PV, SP, and MV data is displayed simultaneously in a 3-row,
negative LCD display with a backlight.
Multiloop control, cascade control, and proportional control are,
possible with a single Controller.
