QNT-1 is a high-precision microprocessor-based device designed for receiving, processing, and displaying signals from incremental encoders or other pulse sensors, with the capability to generate discrete control signals for external equipment.

🎯 Purpose:

The counter provides:

• 📡 Measurement of an input physical parameter (rotation angle, linear displacement, number of revolutions) from an incremental encoder.
• 🧮 Mathematical processing of input data (counting, scaling, filtering) with subsequent display of the current value on the built-in digital indicator.
• ⚡ Generation of discrete output signals for controlling actuators according to user settings.

🚀 Key Features and Functional Capabilities

🔄 Two operating modes:

• 📐 Quadrature counter – operates with two counting inputs (DI1, DI2), determining the counting direction based on the phase shift between the signals.
• 🎛 Command counter – operates with one counting input and a separate command input to set the counting direction.

🔌 Universal inputs:

• Supports connection of PNP/NPN-type sensors, dry contacts, high- and low-level sensors, and incremental encoders.
• 🛡 Galvanic isolation of the inputs ensures protection against industrial interference.

🌐 Data communication interfaces:

• RS-485 with Modbus RTU protocol support for integration into automated process control systems (APCS).
• USB port for direct PC connection and parameter configuration.

💡 Two discrete outputs (DO1, DO2):

Programmable setpoints SET POINT 1 and SET POINT 2 for output activation.

Capability to control loads: ⚙️ switching mechanisms on/off, 📢 signaling, ⏱ generating pulses of a specified duration.
