The Omron H8CA-S is a versatile 1/16 DIN solid-state counter/timer designed for ease of operation, offering a combination of counting and timing functionalities in a single unit. This device is highly adaptable, allowing users to select between preset counter or timer operation modes, making it suitable for a wide range of industrial applications.
The H8CA-S features a clear 6-digit LCD display, with a present value display of 8 mm (0.32 in) and a set value display of 4 mm (0.16 in). A convenient feature of this display is the suppression of non-significant zeros from both the preset and count value displays, enhancing readability. The device supports a broad range of power supply voltages, from 24 to 240 VAC and 12 to 120 VDC, ensuring compatibility with various power systems. For data integrity, it includes memory protection, safeguarding settings and count values even during power interruptions.
For counter functions, the H8CA-S is reversible, offering three input modes and four operating modes to accommodate diverse counting requirements. In timer mode, it supports time-limit operation and integrating operation, also with four selectable operating modes, providing flexibility for different timing scenarios. The device offers four programmable output modes for both counter and timer functions, allowing for customized control logic.
The H8CA-S is designed for surface or flush mounting, providing installation flexibility. Its operating function is selectable between preset counter and timer. The operating system (mode) for the counter includes reversible counting with three input modes and four operating modes, while the timer offers time-limit and integrating operations with four operating modes.
Memory protection is provided by a backup power supply, ensuring data retention for approximately 10 years at 20°C (68°F). The device can count up to 999,999 (6 digits) and offers extensive timing ranges: 0.00 to 9999.99 seconds, 0.0 to 99999.9 minutes, and 0.0 to 99999.9 hours (6 digits). External connection is facilitated via a socket. The display is a 6-digit backlit LCD, showing an 8 mm (0.32 in) present value and a 4 mm (0.16 in) set value.
Input signals for counter functions include count and reset inputs, while for timer functions, start and gate inputs are used. These inputs can be no-voltage (solid-state/contact input) or voltage input. The control output can be either contact or solid-state, depending on the model.
The H8CA-S offers intuitive programming for selecting function modes. To select between timer or counter functions, terminals 1 and 3 must be connected. The device is shipped in counter function, input mode "A," output mode "N," and preset value 1. The "MODE" indicator lights up on the display, and "COUNTS" will blink when the setting key is pressed, allowing the user to navigate to the desired function. Once the function is selected, "COUNTS" will stop blinking, and one of the input modes will begin blinking. The user can then select the desired input mode (e.g., "A") and output mode (e.g., "N"). After setting, terminals 1 and 3 should be disconnected.
Presetting numeric values is straightforward and can be done whether the power supply is ON or OFF. The user can set the desired value by pressing the setting key and incrementing values using the "+" key. Unnecessary higher digits can be preset to 0. If the set value is 0 and the displayed count is also 0, the output will go ON; in this case, pressing reset after presetting will turn the output OFF.
The device's input signals support various configurations. For no-voltage input, the counter output signal is high when the contact turns ON or the open collector transistor is in the ON state, and low when the contact turns OFF or the transistor is in the OFF state. For voltage input, a signal voltage level of 5 to 30 V is considered high, and 0 to 2 V is considered low.
The H8CA-S supports different counter modes:
Output modes include:
The H8CA-S includes power failure detection, indicated by a flickering "PW OFF" display, which alerts users when the control power supply is off. This feature helps in diagnosing power-related issues. The device's memory protection, with a 10-year backup power supply, minimizes data loss during power outages, reducing the need for frequent reprogramming.
For connections, the device provides clear terminal arrangements for power supply, reset input, count input, and control output. When connecting the power supply, it is important to pay attention to polarity for DC-operated models. For external signal input contacts and transistors, it is recommended to use a power supply with an isolated transformer to prevent current feedback and short-circuiting.
When mounting multiple H8CA-S units, specific guidelines are provided to ensure proper engagement and disengagement of hooks, preventing damage and facilitating maintenance. For panel mounting, the Y92F-30 adapter allows for flush mounting, and instructions are given for secure installation and removal.
The H8CA-S has a built-in lithium battery for memory protection. Proper disposal of the old battery is crucial, as lithium batteries can explode if incinerated. This highlights the importance of following environmental guidelines for device maintenance.
Overall, the Omron H8CA-S is a robust and user-friendly device, offering comprehensive counting and timing functionalities with features designed for reliability, ease of use, and straightforward maintenance in industrial environments.
