Digital Controllers
E5AR/E5ER
New DeviceNet-compatible models offer
high-speed and high-precision as general-
purpose Digital Controllers with an even
broader range of application.
Features
■
Easily Coordinate Control with
PLCs Using Various I/O
• Up to 6 Event Inputs
Externally control bank switching (4/8 banks), RUN/STOP, auto/man-
ual, SP mode, communications write enable/disable, and other oper-
ations with event inputs.
■
Control Up to 4 Loops with a
Single Unit
Models with 1, 2, and 4 analog inputs are available (see note). Vari-
ous control modes can also be selected in the software settings,
including standard control, heating/cooling control, cascade control,
position-proportional control, and remote SP control. This allows a
single Unit to perform multipoint control (up to 4 loops for the E5AR,
and up to 2 loops for the E5ER), cascade control, and proportional
control.
Temperature, humidity, and pressure can be controlled simulta-
neously for up to 4 points from a single Unit, contributing to reduced
costs and smaller panels.
Note:
Models with 4 analog inputs are 96 x 96 mm (E5AR only).
Control 4 Loops with a Single Unit
Cascade Control with a Single Unit
• Up to 2 Transfer Outputs
Externally output PVs, SPs, MVs, and ramp SP monitor values for
each loop.
• Up to 4 Auxiliary Outputs
Externally output warnings for 11 alarm modes and input errors.
• RS-485 Serial Communications
Simply share data, such as PVs and SPs, with an OMRON PLC
(without requiring special programming). Only settings are required.

• DeviceNet Communications
Perform high-speed data communications with the PLC without
requiring special programming. Unified management of communica-
tions from a DeviceNet Configurator is also possible.

High-
speed
Applications
•
Bonding equipment
•
Evaporation equipment
•
Coil winding machinery
Problem
Lack of reasonably-priced controller for devices
requiring high-speed response (e.g., ceramic
heaters) resulting in using expensive machinery
with unnecessary functions.
Solution
●
Improved control performance with
high-speed sampling at 50 ms.
●
Moderately priced and easily operated.
High-
resolution
Applications
Problem
Need for high-resolution measuring and
monitoring of internal temperatures of devices
while handling fluctuations at high-resolution.
Solution
Greater input resolution with
Pt sensor (0.01°C resolution)
•
Semiconductor production lines
(exposure, air-conditioning)
•
Environmental testing equipment
•
Vacuum heating furnace
•
Sterilizing equipment
•
Food processing machinery

E5AR Digital Controllers
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.
• Bar graph to show MV (manipulated variable), valve open-
ing, or deviation.
• Multiloop control, cascade control, and proportional control
are possible with a single Controller.
• When using models with communications functions, initial
settings can be downloaded and settings can be masked us-
ing Support Software (Thermo Tools).
• Equipped with calculation functions as a standard (e.g.,
square root calculation and broken-line approximation).
• DeviceNet Communications
Data setting and monitoring can be performed without
special programming.
