The intelligent patrol display alarm instrument is no longer just a simple patrol instrument in the past. Most products in this series of instruments have strong processing capabilities such as calculation, comparison, execution, and alarm. The intelligent touring display alarm instrument adopts a dedicated integrated circuit developed by ourselves and customized by a Japanese integrated circuit manufacturer. It not only gathers most of the functions of various regulating instruments in the current automatic control system, but also integratesCPU, I/O interface, EPROM, and D/A conversion circuits, supplemented by learning from others, carefully programming, and repeated debugging. 1. Measurement accuracy: ± 0 5% FS+1 word 2. Adjust control accuracy: Position: ± 0 5%FS 3. Alarm function: upper limit, lower limit, upper and lower limits, lower return difference, double return difference, etc 4. Input impedance: 0-10mA: 500 Ω, 4-20mA: 250 Ω, thermocouple and DCmV DCmV: ≥ 10K Ω, cold end automatic compensation accuracy: ± 0.3 ℃ within the range of 0-40 ℃ Thermistor: Three wire inputComplete compensation within 3 x ioQ 5. Relay contact capacity: AC220V 2A 6. Power supply: AC220V ≤ 6W ACIIOV DC24V
7. Work environment requirements: temperature 0-50 ℃, relative humidity:<85%, no corrosive gases, no vibration in the workplace
Before installing the instrument, check whether the instrument model, division number, measurement range, and sensor are consistent. 2. The instruments are divided into two types: horizontal and vertical, horizontal rectangular, horizontal square, vertical rectangular, and vertical rectangular. 3. Hole size: a. Horizontal 152 × 76mm (see Figure a) b. Vertical 76 × 152mm (see Figure b) c. Square 92 × 92 (see Figure c) |
