New Product Multifunction Counter/Tachometer H7CX- -N Ultra-compact Counter Provides More Complete Functionality. Basic Features *1 Short body with depth of only 59 mm (for 12 to 24-VDC Models with Screw Terminals). Better readability with character height of 12 mm on 4-digit models and 10 mm on 6-digit models. *2 The present value display characters can be switched between red, green, and orange. Safety and Reliability New set value limit and counter functions have been added. Other Features *3 Front Panel can be changed to white or light gray. New models with two tachometer inputs and two tachometer outputs have *4 been added to the series. For the most recent information on models that have been certified for *1.For 100 to 240-VAC Models with Screw Terminals: 78 mm, Models with Sockets: 63.7 mm safety standards, refer to your OMRON website. (case dimension). *2.The H7CX-A11 and H7CX-R11 have only red characters. *3.The Front Panel can be replaced with an optional Front Panel (except for Tachometer-only Models). Refer to Safety Precautions on page 52. *4.Only one prescale value provided. Features Basic Features Safety and Reliability Ultra Short Body Isolated Power Supply and Input Circuits The body depth has been greatly reduced. Helps in making thinner control panels. Power supply circuit and input circuits are isolated inside the Counter/ Tachometer. Previous non-isolated counters had wiring restrictions 12 to 24-VDC Models with Screw Terminals: 59 mm and could be damaged if wired incorrectly. The H7CX removes these 100 to 240-VAC Models with Screw Terminals: 78 mm* Models with Sockets: 63.7 mm (case dimension) worries. * Power supply circuit and input circuits are isolated for safety and reliability. Note: Except 12 to 24-VDC models. Set Value Limit You can set an upper limit for the set value to prevent unexpected operation of output devices caused by setting mistakes. Previous New models models Easier to Read For better readability, the character height for the present value display is 12 mm on models with 4 digits, the largest class in the industry. The wide viewing angle and brightness provide excellent visibility. The number of display segments has also been increased to Setting the upper limit of the set make settings easier to understand, and the present value display value enables worry-free operation. can be switched between red, green, and orange so that output status can be seen from a distance.
