Description
This Honeywell controller (A4021A1002) is a valve proofing system for gas-burning equipment. It operates on 50 Hz supply with a power consumption of 4.5 W and a low-voltage supply of 24 V. The unit is protected by an external 16 A fuse and an internal 5 A fuse. Its environmental ratings include IP40 ingress protection, an operating temperature range of -10 to 60 °C, storage from -40 to 80 °C, and humidity tolerance up to 95%. Electrical outputs are: valve output 1 A (cos φ 0.7), ignition regulator output 4 A (cos φ 0.7), and alarm output 1 A (cos φ 0.7); vibration resistance is 4.9 N.
