DESCRIPTION
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.
We increased the number of display segments to make setting parameters even easier.
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.
Save Space
A Shorter Body [Make Thinner Panels]
The shorter body enables mounting in thin control panels.
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.
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.

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.
(3) Differential Input for Two Inputs
Measuring the difference between two inputs (CP1 – CP2).
Measuring the difference between two inputs (CP1 – CP2).
(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)).

Using as a Counter *1
| Inputs | CP1, CP2 | (1) In general (except for Dual Counter Mode) Reads counting signals. Increment, decrement, command, individual, and quadrature inputs accepted. (2) When used as a dual counter or twin counter Reads CP1 count signals with CP1 input and CP2 count signals with CP2 input. Increment signals can be input. |
|---|---|---|
| Reset/reset 1 | (1) In general (except for Dual Counter Mode) Resets present value and outputs (OUT2 when using the batch counter) *2. Counting cannot be performed during reset/reset 1 input. Reset indicator is lit while reset input is ON. (2) When used as a dual counter or twin counter. Resets the CP1 present value (to 0). Counting for CP1 input cannot be performed while the reset 1 input is ON. The reset indicator is lit while the reset 1 input is ON. | |
| Total reset or reset 2 | The reset function depends on the selected configuration *3. | |
| Outputs | OUT1, OUT2 | Outputs signals according to the specified output mode when a set value is reached. |
*1. For information on operation of I/O functions, refer to Catalog.
*2. In increment mode or increment/decrement mode, the present value returns to 0; in decrement mode, the present
value returns to the set value with 1-stage models, and returns to set value 2 with 2-stage models.
*3. Reset operates as described in the following table. (The reset indicator will not be lit.)
*2. In increment mode or increment/decrement mode, the present value returns to 0; in decrement mode, the present
value returns to the set value with 1-stage models, and returns to set value 2 with 2-stage models.

| Total and preset counter | Resets the total count value. The total count value is held at 0 while the total reset input is ON. |
| Batch counter | Resets the batch count value and batch output (OUT1). The batch count value is held at 0 while the reset 2 input is ON. |
| Dual counter | Resets the CP2 present value. Counting for CP2 input cannot be performed while the reset 2 input is ON. |
