Large Setting Dial and Moving Pointers Ideal
for Easy Operation and Monitoring
• Incorporating an easy-to-see large setting dial with moving
pointers.
• Wide time-setting range of 0.2 s to 60 h (available through three
time-range model types)
• Wide AC power supply range (100 to 240 VAC)
• IP65 watertight and dust-tight front panel.
• Approved by UL and CSA.
• Conforms to EN61812-1 and IEC60664-1
4 kV for Low Voltage, and EMC Directives.
• Conforms to EMC standards.
• Six-language instruction manual provided.
• Programmable contact enables the building of a self-holding
relay circuit as well as built-in instantaneous contact. (-NS)
• Memory retention (-NSR)
• Finger protection terminal block
• Enables easy sequence checks through instantaneous outputs
for a zero set value at any time range.
For the most recent information on models that have been
certified for safety standards, refer to your OMRON website.
