Precautions when Selecting ZEN Programmable Relays
■ Changes in Comparison with Previous Models
• The power supply and transistor output voltage ranges for CPU Units and Expansion I/O Units with DC power supply has been expanded to
10.8 to 28.8 VDC.
• The width of Expansion I/O Units has been reduced by half and only 8-point models are available.
• The connection method between the CPU Unit and Expansion I/O Units has changed.
• Twin timer operation has been added to timers.
• Multiple-day operation and pulse-output operation has been added to weekly timers.
• An 8-digit counter and 8-digit comparators have been added.
• The accuracy of analog inputs has been increased to
±1.5% FS.
• The timing accuracy of weekly timers and calendar timers has been increased to
±15 s or less per month (at 25°C).
• Australia and New Zealand Daylight Saving Time (DST) settings have been added.
• CPU Units with RS-485 communications and economic CPU Units have been added.
• The heat slits in the cases of CPU Units and Expansion I/O Units have been removed to prevent foreign matter from entering.
Model numbers have been changed to reflect the improved functionality.
