- –AC suffix (for models with LCD Display):
AC supply voltage to use for the VAC L / VAC N terminals (see Electrical specifications)

 

SST-7200D和SST-7400D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。SST-7200(D) & SST-7400(D) accept a pulsed input and provide a 4-20 mA output that is very accurate and stable with temperature changes representing speed of rotating machinery for a local panel meter or PLC analog input card. They also provide 2 “SST-7200(D)” and 4 “SST-7400(D)” quick relay responses to over/under speed conditions. Applications include speed measurement & overspeed protection of industrial engines, turbomachinery and pumps.
