The Siemens 547-314A is a room condition and pressure monitor that excels at precision in various environments. It measures pressure within a full-scale range of +/- 0.5 inches water column (WC), which corresponds to 12.5 Pascal, enabling critical pressure monitoring. The weight of this device is 1.22 lbs, making it relatively lightweight while maintaining robustness.

With an accuracy rating of 0.5% for full-scale readings, this monitor ensures reliable performance in any application. Its excitation voltage operates between 18 and 32 Volts AC, and it functions well within the input frequency range of 50 to 60 Hz.

The device is suitable for operating temperatures ranging from 0 to 50°C specifically for its electronics, and it can withstand storage temperatures from -30°C to 70°C. The humidity tolerance is quite generous, accommodating conditions from 5 to 95% relative humidity without condensation, which broadens its application field.

Power consumption is notably efficient, with a maximum usage of 10 Watts and a typical consumption of 3 Watts, promoting energy savings during operation. For output, the monitor provides options for voltage signals (either 0 to 5 Volts DC or 0 to 10 Volts DC) and current signals rated at 4 to 20 mA, allowing for versatile integration into existing systems.

A 4.3-inch dimmable TFT LCD display with a resolution of 480 x 272 ensures clarity of information for users, enabling easy reading of real-time data. The case of the device is constructed from fire-retardant plastic, classified as UL94 V-0, enhancing safety. Connectivity is made user-friendly with a removable terminal block that simplifies wiring and adjustments.
