CNT-4 is a compact and reliable microprocessor-based device that contains 4️⃣ independent simple pulse counters.
The device is designed for 🧮 counting pulses from primary sensors in order to determine:

  • 📦 the quantity of produced goods (pieces, product groups),
  • 📏 length,
  • ⚖️ weight,
  • 🛢 volume,
  • 🚗 traveled distance.

Distinctive features and functionality:

  • 4️⃣ independent simple counters with the ability to ⏸ stop or 🔄 reset when the set value is exceeded (overflow).
  • 🔌 Universal inputs supporting connection of:
    • 🔵 PNP/NPN-type sensors;
    • ⚪ dry contacts;
    • 💧 high- and low-level sensors.
  • 4️⃣ discrete inputs for implementing control functions (via interface):
    • ▶️ START/STOP — start or stop counting;
    • 🚫 BLOCK — temporary blocking of counting;
    • 🔄 RESET — reset of the accumulated value.
  • 4️⃣ discrete outputs for controlling external loads ⚙️ (actuators, 📢 signaling).
  • 🌐 Communication interfaces:
    • 🔗 RS-485 with Modbus RTU protocol support — for integration into automated control systems;
    • 💻 USB port — for PC connection and parameter configuration.
Inputs:
  • quantity: 4
  • PNP/NPN type
  • =24V
Outputs:
  • quantity: 4
  • transistor OK: up to 40V, 100mA

  • RS-485
  • Modbus RTU protocol.
Counting modes:
  • 4 counters
  • Summation counter
  • DO triggering according to the count setting.
Assembling:
  • on DIN rail
  • 100х55х60 mm.
Power supply:
  • = 24 V, 65mA
