多输出电子压力开关
UDS3 Description
Barksdale的UDS3电子压力开关提供了在一个紧凑的单元中切换四个分立电路的独特能力。除了四个SPDT继电器外，UDS3还标配4-20毫安或0-10伏直流模拟输出和1/2英寸高、易于读取的数字压力显示器。可伸缩的条形图显示提供了更大的可见性。模拟输出可从25%扩展到100%的全可调范围。12位微处理器提供内置诊断，允许开关延时和压力循环高达每秒100次。压力单位可以很容易地在psi、bar、kPa、°C和°F单位之间切换。对于需要精确压力控制、多个开关点和超长寿命的应用，UDS3系列解决方案。Barksdale's UDS3 Electronic Pressure Switch offers the unique ability to switch four discrete circuits in a single, compact unit. In addition to its four SPDT relays, the UDS3 comes tandard with either a 4-20 mA or a 0-10 VDC analog output and a digital pressure display with 1/2" tall, easy-to-read digits. A scalable bar graph display provides even greater visibility. Analog outputs are scalable from 25% to 100% of the full adjustable range. A 12-bit microprocessor provides built-in diagnostics and allows for switch time delays and pressure cycling up to 100 times per second. Pressure units may be readily toggled between psi, bar, kPa, °C and °F units. For applications requiring precision pressure control, multiple switchpoints and extremely long life, the UDS3 Series is the ideal solution.
