Brainchild NC200 Piping Controllers

Brainchil PID Temperature controller NC200The 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
