LAUNCH NOTE

CHRONOS 2 22.5 MM

Introduction: A 22.5mm modular design

Chronos 2 Timers - 22.5mm

• The new 22.5mm is close to identical to the

profile of the 17.5mm Chronos 2:

– Same position of term inal blocks for a perf ect

alignment between the 17.5mm and 22.5mm
timer versions.

– Same appearance in design than the 17.5mm

versions.

Launch Note - Chronos 2 22.5 mm

– A 45mm “nose height” on the front of the

product to allow the mounting of the 22.5mm
versions in modular panels.

– Slightly longer than the 17.5mm versions to

allow the 2 relays SP DT 8A / 250VAC.
