Honeywell 8C-PCNT02

Product introduction

The Honeywell 8C-PCNT02 is a compact yet powerful counter module designed for integration into Honeywell’s Series 8 control systems, serving as a critical component in industrial counting and monitoring applications. This module is engineered to accurately track and process digital input signals, making it indispensable in scenarios where precise event counting is essential for process control and optimization.

Equipped with two isolated digital inputs, the Honeywell 8C-PCNT02 offers versatile counting capabilities, supporting up/down counting modes to adapt to diverse industrial needs. Its seamless integration with Series 8 controllers ensures that count data is readily available for system-wide analysis and decision-making. By providing real-time count information, the Honeywell 8C-PCNT02 helps operators maintain tight control over production quantities, material usage, and equipment cycles, ultimately enhancing operational efficiency and reducing waste.

Core advantages and technical highlights

High counting precision: The Honeywell 8C-PCNT02 delivers reliable counting up to 10 kHz, ensuring accurate tracking even in high-speed applications such as conveyor belt part counting or fast-moving assembly lines. Its 8-digit count range (0-99999999) accommodates large production runs without overflow issues, eliminating the need for frequent manual resets. This precision is critical in industries like automotive manufacturing, where counting components per assembly must be exact to avoid quality defects.

Input isolation: With 2500 VAC isolation between channels and ground, the Honeywell 8C-PCNT02 protects against electrical noise and ground loops common in industrial environments. This isolation prevents signal interference from nearby motors, transformers, or high-voltage equipment, ensuring consistent counting accuracy. In facilities with complex electrical systems, this feature reduces downtime caused by false counts or module malfunctions.

Flexible operation: The Honeywell 8C-PCNT02 supports multiple counting modes—up, down, and up/down—making it adaptable to various applications. For example, in inventory management systems, it can count incoming (up) and outgoing (down) items to maintain real-time stock levels. The module’s compatibility with 12-24 VDC inputs allows it to connect to a wide range of sensors, including photoelectric, inductive, and mechanical switches, enhancing its versatility.

Compact and rugged design: Measuring just 110mm x 75mm x 60mm, the Honeywell 8C-PCNT02 fits easily in crowded control cabinets, saving valuable space. Its DIN rail mounting simplifies installation and allows for quick integration into existing systems. The module operates reliably in temperatures from 0°C to 60°C and withstands high humidity (5-95% non-condensing), making it suitable for harsh industrial environments like food processing plants or chemical facilities.

Typical application scenarios

In packaging industries, the Honeywell 8C-PCNT02 is used to count the number of products passing through packaging lines. Mounted near photoelectric sensors on conveyor belts, it tracks individual items as they move to packaging stations. By presetting a target count (e.g., 100 units per case), the module triggers a signal to stop the conveyor or activate a labeling machine once the target is reached, ensuring consistent package quantities and reducing over-packaging waste.

Within material handling systems, such as warehouse distribution centers, the Honeywell 8C-PCNT02 monitors the number of pallets or containers moved by automated guided vehicles (AGVs). Using inductive sensors to detect metal tags on AGVs, the module counts each pass, providing data to manage workflow and prevent bottlenecks. Its up/down counting mode allows operators to track items entering and exiting specific zones, optimizing storage space utilization.

In manufacturing quality control, the Honeywell 8C-PCNT02 counts the number of parts inspected by automated testing equipment. For each defective part detected, it increments a separate counter, enabling operators to monitor rejection rates in real time. This data helps identify production issues early, reducing the number of faulty products reaching customers and improving overall quality metrics.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the Honeywell 8C-PCNT02, ensure the DIN rail is securely mounted in a clean, dry control cabinet with adequate ventilation. Verify the ambient temperature is within 0°C to 60°C and humidity is 5-95% non-condensing. Gather tools: DIN rail cutter (if needed), screwdriver, and multimeter. Check that the 12-24 VDC power supply is properly fused and grounded. Review the wiring diagram to connect sensor inputs to terminals, ensuring correct polarity and avoiding crossing with high-voltage cables to prevent interference.

Maintenance suggestions: Inspect the Honeywell 8C-PCNT02 monthly for loose connections or dust accumulation; use compressed air to clean vents if necessary. Test input signals periodically with a multimeter to ensure sensors are sending proper 12-24 VDC pulses. If counting errors occur, check for sensor misalignment, electrical noise (use oscilloscope if needed), or incorrect mode settings. Reset counts via the connected controller or HMI when needed. For firmware updates (if applicable), follow Honeywell’s instructions to avoid module damage. Replace the module only when power is disconnected to prevent electrical shock.
