The NC200 is a compact fuzzy logic plus PID temperature controller with J or K type thermocouple or RTD input. Multiple units (up to 247 units) can be networked together with a 4P4C modular connector. Each unit auto-tunes on the initial setup to provide the best response for each heater. The NC200 is powered by 90-250VAC supply and contains a solid-state relay as its control output. The solid-state relay can drive the heater directly through a plug-in connector. The major

Features

    • Compact size
    • Auto addressing, manual setting unnecessary
    • Network up to 247 controllers
    • The fastest speed, taking 1 second to update 1000 data
  • Used with SCADA, HMI via Modbus RTU
  • Quick connector for easy and safe wirings
