553-03

产品型号：553-03 产品名称：553-03 产品分类：Time Delay Relays 品牌：Time Mark Corporation（美国时间标记公司） 产品简介：The Model 553-03 Re-Acceleration Relay is designed to take the place of a voltage sensing relay and two time delay relays. When voltage is applied to the Model 553-03, and the external start switch is closed, the adjustable on-delay time begins. After the delay period, the contacts will close. If the line voltage drops below 90 volts, the contacts open and the true-off delay begins. If the voltage rises above 102 volts before the true-off delay has elapsed, the contact will re-close. If voltage is not restored to 102 volts before the true-off delay time period ends, the contacts will remain open until the external start switch is closed. 技术参数：Mount: 8-Pin; Timing Range: On delay: 0.1-40 Sec. Off delay: 1-10 Sec.; Timer Function: Re-Acceleration Relay; Voltage Range: 120VAC 应用领域：广泛应用于电机启动延时、照明控制、 HVAC系统、工业自动化、安全联锁等需要时间延迟控制的场景 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
