该dra-act-2i和dra-act-2v系列是孤立的双线回路供电的交流电流、交流电压输入din导轨安装信号调节器，将测得的输入成比例的，线性的和高度精确的4-20ma输出电流。交流输入电流模型的dra-act-2i系列包括0对aac和0～5aac输入4至20毫安输出模型。输入交流电压模型的dra-act-2v系列包括0 150伏模型，0到0伏和400vac的输入4到20毫安输出再次。
为完全安全，变压器内部分离输出使这些单位承受很大的瞬时输入输入信号调节器。完整的输入输出隔离，高浪涌电流能力和高的输出信噪比使这些信号调节器接地回路信号和rfi高度免疫。这些发射机还配备了一个“测试”终端使该输出电流监测通过测量压降，内部10欧姆的电阻不影响4到20毫安的过程回路。
