CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The Electronics Unit processes sensor signals, runs control algorithms, and drives the valve actuator to regulate gas flow precisely. It interfaces with the sensor, valve, and external control systems.
It requires a 24 V DC supply (24 ±10%) with reverse polarity protection, consumes ≤5 W at nominal voltage, and offers analog output (0–5 V DC or 4–20 mA) and digital communication (RS-485 or DeviceNet with Modbus RTU).
It operates at -10 to 50 °C, stores at -20 to 70 °C, and tolerates non-condensing humidity up to 90% RH. The housing is IP40 rated for indoor use.
It has an accuracy of ±0.5% of setpoint (including linearity and repeatability) and repeatability of ±0.1% of full scale under constant conditions. Response time is ≤100 ms to 63% of final value.
