Multifunction Preset Counter


DIN 48 × 48 mm Multifunction Preset Counter with a Bright, Easy-to-view, Negative Transmissive LCD

Easier to Read

Character Height: 12 mm [Large Characters]

The larger characters and wider viewing angle join a bright display for easy reading even in well-lit locations.

H7CX-A Features 2

We increased the number of display segments to make setting parameters even easier.

H7CX-A Features 3

Orange Added to Switchable Display Colors to Readily Show the Output Status [Status Monitoring]

Using Green When Output Is OFF Using Orange When Output Is ON
*Display colors can be switched only on models with terminal blocks.

H7CX-A Features 4

Save Space

A Shorter Body [Make Thinner Panels]

The shorter body enables mounting in thin control panels.

H7CX-A Features 6

Models with terminal blocks for 12 to 24 VDC. (Shortest Body)

At only 59 mm, the shortest body for any industrial counter.

Models with terminal blocks for 100 to 240 VAC. (Shortest Body)

At only 78 mm, the shortest body for any industrial counter that isolates the power supply and input circuits.

*Models with Sockets: 63.7 mm (case dimension)

The above claims apply to counters with a maximum ambient temperature of 55 ºC.
According to OMRON investigations June 2009.

Safe and Reliable

Setting Upper Limit [Prevent Unexpected Operation]

Restricting the set time help prevent incorrect settings.

Output ON Count Alarm Indication [Service Life Notification]

The number of times that the control output turns ON is counted and an alarm is displayed when a preset count is exceeded.

More Complete Lineup

Twin Counter Mode [One Unit, Two Counters]

A Twin Counter Mode has been added to enable using two counters with only one unit.

*Only two-stage models.

Replaceable Front Panel [Design Flexibility]

Replace the front panel with an Optional Front Panel to change the basic color from black to light gray or white.

• Optional Front Panels let you match the color of the panel or surrounding devices.

H7CX-A Features 14

Waterproof, Dust-proof Structure (UL508 Type 4X and IP66) [Design Flexibility]

Worry-free application is possible in locations subject to water.

*When the Y92S-29 Waterproof Packing is used.

H7CX-A Features 15

More Complete Tachometer Functionality


A Wide Range of Input Modes

New input modes have been added to the new models.
Now you can handle a wider range of applications.

(1) One-input measurement
       Measurement operation with one input.
       Select the HI-LO, AREA, HI-HI, or LO-LO output mode.

(2) Independent Measurement for Two Inputs
       Measurement operation with two independent inputs.

H7CX-A Features 19

       Measuring the difference between two inputs (CP1 - CP2).

H7CX-A Features 20

(4) Absolute Ratio for Two Inputs
      Measuring the ratio between two inputs (CP1/CP2).

(5) Error Ratio between Two Inputs
      Measuring the ratio between two inputs ((CP1-CP2)/CP2)).
