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.
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.
The information in this document applies to V2 Units.
Refer to page 28 for details on differences with previous
products.
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.
