448

产品型号：448 产品名称：448 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 448 Output Relay Board provides electromechanical relay contacts for the Model 404 or 408 Liquid Level Sensors, allowing those models to be used as a control device. The Model 448 consists of a power supply and five relays on the surface-mounted printed circuit board. Four of the five relays are used with the Model 404. All five relays are used on the Model 408, refer to typical application. Some liquid level control applications may not require the alternating control, HOA switches, or run-time meters (see the Model 403 or Model 407 data sheets). The Model 404 and Model 408 Liquid Level Sensors uses the Model 448 to meet the needs of direct relay control applications. 技术参数：Voltage Range: 105-130VAC 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
