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.
■ 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.
• Multiple-day operation and pulse-output operation are now
• These improved functions are convenient for time-controlled
Economy-type Added to the Series
• Economy-type CPU Units with a more affordable price have been
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).

Other Versatile Functions
• Use of a Memory Cassette makes it easy to copy and save
• Equipped with two analog input channels (CPU Units with DC
• Password function ensures security. (See note.)
• Multi-language display in six languages (English, Japanese,
• Display user-set messages or analog-converted values. (See note.)
Note: Not supported for ZEN-@C2@@-@-V2 models.
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
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.
Twin-timer Operation Added
Twin-timer operation allows you to set ON and OFF times separately,
greatly simplifying intermittent operation.
DC power supply models are equipped with two analog inputs (0 to
