Product Code: SST-7400D
产品简介：
Dynalco SST-7400D是一个可编程的PC，安装在DIN轨道上的速度开关，具有显示和键盘编程功能。它有4个标准继电器，通过提供可靠的欠速/超速保护来保护旋转设备免受故障的影响。SST-7200（D）和SST-7400（D）接受脉冲输入，并提供4-20mA输出，该输出非常精确和稳定，温度变化代表本地面板仪表或PLC模拟输入卡的旋转机械速度。它们还提供2个“SST-7200（D）”和4个“SST-7400（D）”快速继电器对超速/低速条件的响应。应用范围包括工业发动机、涡轮机械和泵的速度测量和超速保护。Dynalco SST-7400D is a PC-programmable, DIN rail mounted speed switch with display and keypad programmability. It has 4 standard relays to protect your rotating equipment from failure by providing reliable under/over speed protection。
