Even Broader Applications with Increased
Functionality and Higher Precision
• Increased functionality in a compact body (70 mm wide × 90 mm
high).
• Easy programming is available using the LCD and operation
buttons. (See note 1.)
• This single Unit easily provides relay, timer, counter, and time
switch functions.
• Expansion is easy with Expansion I/O Units, allowing up to 44
I/O points. (See note 2.)
• Economy-type and Communications-type CPU Units have been
added to series.
• Improved Weekly Timers (See note 1.)
Increased timing accuracy with a monthly deviation of ±15 s
max. Multiple-day operation and pulse output operation have
been added.
• Select from two power supply options:
100 to 240 VAC or 12 to 24 VDC.
Note: 1. Not supported for ZEN-@C2@@-@-V2 models.
2. When using CPU Units with 20 I/O points.
The information in this document applies to V2 Units.
Refer to page 28 for details on differences with previous
products.
Features
■ Easy and Simple Programming for Automatic Small-scale Control
Saves Space, Wiring, and Installation Steps
• Versatile functionality in a compact body (70 mm wide × 90 mm
high).
• This single Unit easily provides relay, timer, counter, and time
switch functions. Wiring work is greatly reduced because separate
wiring is not required for devices such as timers and counters.
90 mm
70 mm
Easy Programming
The LCD screen comes with 8 operation buttons on the front panel to
enable programming in ladder view format. The LCD screen also has
a backlight, making it easier to see when the ZEN is used in dark
locations.
Note: Not supported for ZEN-@C2@@-@-V2 models.
Programmable Relay ZEN V2 Units1
Flexible Expansion Enables Up to 44 I/O
Points
Up to three Expansion I/O Units can be connected if there are not
enough I/O points. Expansion I/O Units are only 35 mm wide.
Note: CPU Units with 10 I/O points can be expanded to 34 I/O points.
Expansion I/O Units cannot be connected to Economy-type
CPU Units.
Support Software with Simulation Function
• Programs can be easily written, saved, and monitored by personal
computer.
• Programs can be simulated on the personal computer without
connecting to the ZEN.
Note: For notebook computers that do not have an RS-232C serial
port, connect the computer to the ZEN by connecting an
OMRON CS1W-CIF31 USB-Serial Conversion Cable to the
ZEN-CIF01 Connecting Cable.
Other Versatile Functions
• Use of a Memory Cassette makes it easy to copy and save
programs.
• Equipped with two analog input channels (CPU Units with DC
power supply only).
• Password function ensures security. (See note.)
• Multi-language display in six languages (English, Japanese,
German, French, Spanish, Italian). (See note.)
• Display user-set messages or analog-converted values. (See note.)
Note: Not supported for ZEN-@C2@@-@-V2 models.
■ Enhanced Features of V2 CPU Units
Improved Weekly Timer and Calendar Timer
Functions
Note: Not supported for ZEN-@C2@@-@-V2 models.
• The time precision has been increased.
Conventional model: 2-min difference/month
↓
-V2 models: ±15-s difference/month (at 25°C)
• Multiple-day operation and pulse-output operation are now
possible.
• These improved functions are convenient for time-controlled
applications such as lighting and air conditioning control.
Lighting controlAir conditioning control
Economy-type Added to the Series
• Economy-type CPU Units with a more affordable price have been
added to the series, although Expansion I/O Units cannot be
added.
RS-485 Communications Model Added to
Series
Production line conditions can be remotely monitored by monitoring
the ZEN control status.

More Precise Analog Input
Conventional model: ± 10% FS → -V2 models: ± 1.5% FS
DC power supply models are equipped with two analog inputs (0 to
10 V). There are four analog comparators. The increased precision
makes it even easier to use the Unit in simple control applications
with voltage, current, temperature, and other analog values.
8-digit Counter, 150-Hz Counter
• An 8-digit counter and 8-digit comparator have been added.
• The maximum count for DC power supply models is 150 Hz.
12 to 24 VDC Line Voltage Operation
Operation is now possible with 12 VDC.
Expansion I/O Units have been reduced to
half-size (35 mm wide).

Twin-timer Operation Added
Twin-timer operation allows you to set ON and OFF times separately,
greatly simplifying intermittent operation.

The life under the worst conditions, of the output contacts used in
ZEN relay outputs is given in the above table. Guidelines for the
normal life of the relays are shown in the diagram on the right.
Note: The switching capacity, switching durability, and applicable
load area when actually using the relay depend on the type of
load, environmental conditions, and switching conditions.
Therefore, be sure to confirm these conditions for the actual
