2734

产品型号：2734 产品名称：2734 产品分类：Current Monitors 品牌：Time Mark Corporation（美国时间标记公司） 产品简介：The Model 2734 Current Sensitive Relay monitors a single-phase AC current for an over-current condition. A top-mounted current transformer (CT) provides complete isolation from the control voltage as well as easy installation. Operation begins when the current being monitored rises to 10% of the trip setting, which initiates the start-up delay. When the delay expires, over-current sensing begins. In the AUTO mode, the Model 2734 resets when current drops below the trip setting. In the MANUAL mode, the unit must be reset by momentarily switching to the AUTO mode, and back, after the current fault is cleared. The TRIPPED LED indicates the output relay status. Current must drop below 10% of the trip setting for the start-up delay to restart. The standard model operates in a non-failsafe mode; if control power is lost, over-current detection is lost. A failsafe option is available, fixed or switchable. An adjustable dead band option is also available. 技术参数：Contacts: SPDT; Mount: Surface Mount; Trip Delay: Yes; Current Input: 5A , 10A , 20A; Voltage Range: 21-140VAC 应用领域：适用于电机过载保护、电流监测、负载状态检测、节能控制、设备状态监控等电流监测场景 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
