Omron H7CX-W DATASHEET

New Product

Multifunction Counter/Tachometer

H7CX-@-N

Ultra-compact Counter Provides More Complete Functionality.

Basic Features

• 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.

• 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

• Front Panel can be changed to white or light gray.

• Models with two independent tachometer inputs have been added to the series.

*1.For 100 to 240-VAC Models with Screw Terminals: 78 mm, Models with Sockets: 63.7 mm (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.

Features

Basic Features

Ultra Short Body

The body depth has been greatly reduced. Helps in making thinner control panels.

12 to 24-VDC Models with Screw Terminals: 59 mm 100 to 240-VAC Models with Screw Terminals: 78 mm* Models with Sockets: 63.7 mm (case dimension)

* Power supply circuit and input circuits are isolated for safety and reliability.

New 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 make settings easier to understand, and the present value display can be switched between red, green, and orange so that output status can be seen from a distance.

Safety and Reliability

Isolated Power Supply and Input Circuits

Power supply circuit and input circuits are isolated inside the Counter/ Tachometer. Previous non-isolated counters had wiring restrictions and could be damaged if wired incorrectly. The H7CX removes these worries.

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.

Setting the upper limit of the set value enables worry-free operation.

For 1,000 pieces

Output Counter

The output counter counts the number of times the output turns ON (alarms can be displayed and the count can be monitored in increments of 1,000 operations). This counter is useful in managing the service life of the Counter/Tachometer or the load.

No overflow

The Easiest Operation

Operation is simplified by the Up/Down Key for each digit on 4-digit models and Up Key for each digit on 6-digit models.

Other Features

The front color can be changed simply by replacing the Front Panel.

The Front Panel can be replaced with an optional Front Panel (sold separately) with a different color to match the installation site. Select from black, white, and light gray (except for models with tachometer function only).

(Standard)

White

Only the Front

Panel can be

Universal NPN/PNP Input

DC 2-wire sensors can be connected for a wide range of input devices.

Waterproof, Dust-proof Structure (UL508 Type 4X and IP66)

Worry-free application is possible in locations subject to water. Note: When the Y92S-29 Waterproof Packing is used.

Key Protection

Select from any of seven protection patterns. Use the best one for the application.

New Functions

Many useful functions have been added, including a Twin Counter Mode and many tachometer functions to handle even more applications. New Tachometer Functions

• Control with two independent inputs (independent measurements, differential, absolute ratio, and error ratio)

• Peak/bottom hold function

• Output hysteresis setting

• Output OFF delay

• Switching the measurement method (pulse cycle/pulse width)

• Startup time

• Auto-zero time

• Averaging method/Number of averaging times

• AMD-compatible Mode

You can change the color of the Front Panel when mounting the Counter/Tachometer. The Counter/Tachometer is shipped with a black (N1.5) Front Panel. "COUNTER" is printed on the front of Replacement Front Panels.

Replacement Method

The Front Panel is attached to the Counter/Tachometer with tabs in four locations. To remove the Front Panel, open the tabs and pull the Front Panel forward. To attach the Front Panel, press it

Ta bs

onto the Counter/Tachometer so that all four tabs lodge into the grooves on the body of the

Grooves

Counter/Tachometer.

Protecting the Counter/Tachometer in Environments Subject to Oil

The H7CX's panel surface is water-resistive (conforming to IP@6, UL Type 4X) and so even if drops of water penetrate the gaps between the keys, there will be no adverse effect on internal circuits. If, however, there is a possibility of oil being present on the operator's hands, use the Soft Cover. The Soft Cover ensures protection equivalent to IP54F against oil. Do not, however, use the H7CX in locations where it would come in direct contact with oil.

Flush Mounting Adapter

Y92F-30

Order the Flush Mounting Adapter with the following model number separately if it is lost or damaged.

Note: The

Waterproof Packing is included with models with screw terminals.

Y92F-45

Use this Adapter to install the Counter/ Tachometer in a cutout previously made for a DIN 72 × 72 mm device (panel cutout: 68 × 68 mm).

Waterproof Packing

Y92S-29

Note: The

Waterproof Packing is included with models with screw terminals.

The Waterproof Packing will deteriorate, harden, and shrink depending on the application environment. To ensure maintaining the IP@6, UL Type 4X waterproof level, periodically replace the Waterproof Packing. The periodic replacement period will depend on the application environment. You must confirm the proper replacement period. Use 1 year or less as a guideline. If the Waterproof Packing is not replaced periodically, the waterproof level will not be maintained. It is not necessary to mount the Waterproof Packing if waterproof construction is not required.

Order the Waterproof Packing separately if it is lost or damaged. The Waterproof Packing can be used to achieve IP66 protection.

• DIP switch settings are effective when the power is turned ON again. (Perform DIP switch settings while the power is OFF.)

Step2

The H7CX-A@-N is a Counter that contains more than one functional counter.

When using the Counter in any mode other than the default mode*, use the following chart to enter

Configuration Selection Mode and set the functions that are suitable to the application.

* The default mode is 1-stage preset counter configuration (2-stage preset counter configuration for 2-stage models).
