Do you have a question about the Panasonic LC2H Series and is the answer not in the manual?

The Panasonic LC2H DIN Half Size LCD Counter is a versatile and compact digital counter designed for various industrial and commercial applications. It features an easy-to-read 8.7 mm (0.343 inch) character height, an increase from the previous 7 mm, ensuring clear visibility of the 8-digit display.

Function Description:

The LC2H counter is primarily used for counting events, with the ability to switch counting speeds between 2 kHz and 30 Hz, making it adaptable to different application requirements. It supports multiple input methods: non-voltage input, voltage input (4.5 to 30 V DC), and free voltage input (24 to 240 V AC/DC). This broad compatibility allows for integration into diverse control systems. The counter includes a front reset button for manual resetting of the count value, which can be disabled via a lock switch for security. For backlight models, the display is easily viewable in dark conditions and can be switched between green and red, enhancing user experience.

Important Technical Specifications:

General:

No. of Digits: 8 digits
Character Height: 8.7 mm (0.343 inch)
Compliance: UL, c-UL, CE compliant.
Protective Construction: Conforms to IP66 (front panel surface, for installation frame type only).
Panel Covers: Replaceable (standard ash gray, with an optional black panel cover).
Screw Terminals: Designed with finger protection for safety.

Counting Speed:

Switchable: 2 kHz / 30 Hz (via switch).
Min. Input Signal Width (ON:OFF = 1:1): 0.25 ms / 16.7 ms (switchable by switch) for non-voltage and voltage input types. 16.7 ms for free voltage type (at 30 Hz).

Input Methods:

Non-voltage Input Type:
- Input Method (signal): Using contacts or open collector connection.
- Input Impedance: Max. 10 kΩ (when shorted), Max. 750 kΩ (when open).
- Residual Voltage: Max. 0.5 V.
- Reset Input: Same specifications as count input. Min. input signal width 200 ms.
Voltage Input Type (4.5 to 30 V DC):
- Input Method (signal): High level: 4.5 to 30 V DC, Low level: 0 to 2 V DC.
- Input Impedance: Approx. 4.7 kΩ.
- Reset Input: Same specifications as count input. Min. input signal width 200 ms.
Free Voltage Input Type (24 to 240 V AC/DC):
- Input Method (signal): High level: 24 to 240 V AC/DC, Low level: 0 to 2.4 V AC/DC.
- Input Impedance: Approx. 4.7 kΩ.
- Reset Input: Same specifications as count input. Min. input signal width 200 ms.

Display:

Display Method: 7-segment LCD.
Backlight Type: 7-segment LCD with green/red backlight (for voltage input type only).
Backlight Power: 24 V DC (±10%).

Environmental Conditions:

Operation Temperature: -10 to +55°C (+14 to +131°F) (without frost or dew).
Storage Temperature: -25 to +65°C (-13 to +149°F) (without frost or dew).
Ambient Humidity: 35 to 85% RH (non-condensing).
Vibration Resistance: Functional: 10 to 55 Hz (1 cycle/min.), single amplitude: 0.15 mm (10 min. on 3 axes). Destructive: 10 to 55 Hz (1 cycle/min.), single amplitude: 0.375 mm (1 hr. on 3 axes).

Breakdown Voltage: Between charged and uncharged parts: 1,000 V AC for 1 minute (2,000 V AC for free voltage type).

Battery Life:

Panel Mounting Type: 7 years (at 25°C / 77°F) for non-backlight models, 6 years (at 25°C / 77°F) for backlight models. (Note: Battery life is calculated based on continuous operation with count input signal ON/OFF = 1:1 and is not guaranteed. It decreases by 30% when operating continuously in 2 kHz mode.)
PC Board Mounting Type: External power supply (3V DC) required. Max. 30 µA current consumption (max. 250 µA during reset input).

Usage Features:

Two Installation Methods: The panel mounting type offers both a one-touch installation for quick setup and an installation frame type that uses a bracket for secure mounting. This allows users to choose the method best suited for their application.
Easy-to-Read Display: The increased character height and optional backlight ensure clear visibility of the count value, even in challenging lighting conditions.
Flexible Input Options: With non-voltage, voltage, and free voltage input methods, the LC2H can be integrated into a wide range of existing systems.
Count Speed Switch: The ability to switch between 2 kHz and 30 Hz counting speeds provides flexibility for applications requiring different response times.
Lock Switch: The front reset button can be locked to prevent accidental resets, enhancing operational security.
Connected Installation (Sealed Installation): For installation frame types, multiple units can be installed side-by-side while maintaining waterproofing, suitable for environments requiring sealed enclosures.

Maintenance Features:

Easy Battery Replacement: For the one-touch installation type, the body can be easily removed to replace the battery. For the installation frame type, the battery lid can be removed for replacement. This design simplifies maintenance and minimizes downtime.
Replaceable Panel Covers: The standard ash gray panel cover can be replaced with an optional black panel cover, allowing for aesthetic customization or replacement of damaged covers.
RoHS Directive Compatibility: Information on RoHS Directive compatibility is available online, ensuring adherence to environmental standards.

The LC2H is a robust and user-friendly counter, ideal for applications requiring reliable event counting with flexible installation and input options, all while adhering to international safety and environmental standards.
