Solid-state Counter
H7CN
CSM_H7CN_DS_E_2_2
All Required Counter Functions
Incorporated in a Compact DIN-sized
(48
×
48) Housing
• In addition to Up and Down models, a reversible (Up-Down)
counter is also available
• Maximum counting speed of 5,000 cps, never before attained
by a small-size preset counter
• Power supply freely selectable within a range of 100 to 240
VAC. Also, power supply for the DC-operated models is
selectable within a range of 12 to 48 V
• Models with memory backup function against power failure
available
For the most r ecent information on models that have been certified for
safety standar ds, refer to your OMRON website.
