662

产品型号：662 产品名称：662 产品分类：Liquid Level Controls 品牌：Time Mark Corporation（美国时间标记公司） 产品简介：The Model 662 Pump Up Control, part of the 600 series line of instrumentation controls, is designed to monitor andmaintain liquid levels. A user-provided 4-20mA current loop represents the liquid level, and output connections are provided for pump control. The HIGH ADJUSTsetpoint, and the LOW ADJUST setpoint, are field adjustable. If the input falls below the low setpoint, the PUMP UP relay energizes, and remains that way until the input rises above the high setpoint. The high setpoint must always be set above the low setpoint. Top-mounted LEDs on the Model 662 show system status. The PUMP UP LED turns ON when the input falls to 10% below the low setpoint, and resets when the input rises above this level. An INPUT LOOP ERROR LED turns ON if the input is outside the 4-20mA range. A Time Mark Model 650 Loop Power Supply (or equivalent) is required to provide the 24 VDC operating voltage. A Time Mark Model 672-15 Pressure Transducer (or equivalent) is required to provide the input signal. 技术参数：Voltage Range: 24VDC 应用领域：适用于水箱液位控制、泵阀自动控制、工业储罐液位监测、给排水系统等液位控制场景 产品特点：美国原装进口，品质可靠；DIN导轨安装，方便集成；LED状态指示，直观易读；宽电压范围，适应性强；工业级设计，经久耐用
