【英文介绍】
Allen-Bradley 2711P-T7C21D8S belongs to the PanelView Plus 7 operating terminal. The operating terminal features a 6.5-inch color display with a viewing area of 132 x 99 mm, a resolution of 640 x 480 VGA, 18-bit color graphics, and an aspect ratio of 4:3. An analog resistive touch input area is installed on the same display, allowing the operator to directly touch the corresponding runtime object to initiate functions such as control, navigation, data modification, etc. This embedded touch interface can be driven up to 1 million times with the equivalent of 100 grams of actuating force.
The Allen-Bradley 2711P-T7C21D8S is fitted with a battery-powered real-time clock (RTC) with an accuracy of ±2 minutes per month at 25 °C (77 °F) and a life expectancy of at least 4 years. It also comes with internal memory, such as 512 MB of random access memory (RAM), 512 MB of storage and 80 MB of user memory for file storage. Additionally, external SD cards and USB flash drives can be installed to provide higher storage memory.
The 2711P-T7C21D8S is powered by an external power supply of 18-30VDC with a nominal value of 24VDC. It has a maximum power consumption of 50W. When mounting this operating terminal flush into the cabinet, create a panel notch measuring 142 x 184 mm (5.59 x 7.24 in).
Suitable housings for use with operating terminals are electrical panels with protection grades NEMA and UL Type 12, 13, 4X (indoor use only), which are also IP54 or IP66 in the UL classification.
The 2711P-T7C21D8S operates in A voltage range of 18 to 30 volts DC, with a maximum power consumption of 35 watts at 1.46A and 24 volts DC, and a maximum power consumption of 85 to 265 volts AC at a 47 to 63 Hertz guide power supply. It operates in a temperature range of 32 to 131 degrees Fahrenheit, has a relative humidity of 5 to 95 percent, and is stored in a temperature range of -13 to 158 degrees Fahrenheit. It dissipates a maximum of 15 watts of heat during operation and is designed to withstand 15 g of operating shock and 2G of 57 to 600 Hz operating vibration. It comes in NEMA grade 4X, 12 and 13 enclosures and is cUL-us, ATEX, CE, KCC and RoHS certified. The 2711P-T7C21D8S weighs approximately 0.85 kg (1.86 lb) and has a net size of 170 x 212 x 56.5 mm (6.69 x 8.35 x 2.22 in).
