1.8.7 mm/ .343 inch Character Height (previously 7 mm)

Easy-to-read character height increased from 7 mm to 8.7 mm/ .276 inch to .343 inch.

 

2.Plenty of Digits

 

3.Counting Speed Switchable between 2 kHz and 30 Hz

4.Panel Mounting Type Features 2 Installation Methods

Comes with very easy one-touch installation type and also installation frame type that uses the bracket on the timer/counter.
Choose a method that suits the application.

 

5.Battery Replacement Easy on Environment

To replace battery simply remove body for the one-touch installation type, and remove battery lid for the installation frame type.

 

6.Screw Terminals Designed for Safety

Built in finger protection.

 

7.Panel Covers Replacable(Standard color is ash gray.)

Change the panel design by replacing with a black panel cover.

 

8.Conforms to IP66 Protective Construction (Only installation frame type.) (Front panel surface)

 

9.Input Methods

  • 1.Non-voltage input method
  • 2.Voltage input method
  • 3.Free voltage input method

 

 

10.Backlight Type Added to Series and Now 2-color Switchable (green/red)

Easy viewing even in dark places and switchable between green and red(Voltage input type).

 

11.Compliant with UL, c-UL and CE.

Explanation of Operation

Note) * Count becomes “1” when the reset input is turned OFF while the count signal is being input.

1.Counting takes place when the count input signal is ON.

2.Counting resumes again when the count value reaches 99999999 (full scale value) and then returns to “0” with a new count input.

3.No measurement takes place when a reset is input.

  • 1.When reset is ON, resetting takes place and the count becomes “0”.
  • 2.Press the front reset button when you want to reset manually (only panel installation type).

Note)Be aware that battery life will decrease if the count input or reset input are left ON.

Notes:-

  1. The value given for battery life is calculated based on continuous operation (count input signal ON/OFF = 1:1), therefore, this value is not guaranteed. Also, battery life is decreased 30% when operation is continuous with 2 kHz count inputting in 2 kHz mode.
  2. Operation is at 25 Hz when using 24 V AC
  3. Only for installation frame type
