7B系列的最大非线性误差为±0.02%,并经过工厂校准,保证最大±0.1%的精度特性。与多用途信号调理器或自有设计相比,其性能更出色,成本更低。7B系列模块提供1500 V rms隔离和120 V rms现场接线输入保护。此外,驱动模块各输入电路所需的电源均在内部进行隔离,因此7B系列模块能够为输入信号提供真正的通道与通道隔离。这些模块的标称额定输入为+24 V直流电源;为获得最大的灵活性,它们接受+14 V至+35 V范围内的直流电源电压。
所有模块都封装在紧凑的2.1" x 1.7" x 0.6" (54 mm x 42 mm x 14 mm)耐用塑料外壳中,能够轻松支持高通道密度应用。每个模块都可以在高湿度(非冷凝)环境下工作,额定温度范围为–40°C至+85°C工业温度范围。所有模块都采用简单的引脚排列,可以混搭用于单个背板设计中。此外,模块可以在通电情况下插入背板或从中拔除,维护方便。
