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.
