LAC® 65.1 Scope: The load to Analogue Converter is a highly reliable device, which can link analogue transducers to various analogue equipments. The LAC produces both voltage and current loop outputs and allows a wide range of filter, off-set and gains settings to suit any industrial application. Because of the AC load cell excitation and the galvanically isolated power supply. The LAC rejects unwanted influences and disturbances better than any comparable device. These features plus the ratiometric design (which include the add-on optional modules) ensure high accuracy and reliability. Additional safety features ensure that if a fault occurs with either the load cell or its connections, the LAC will fail-safe. This is particular important in safety critical applications. 范围：范围：负载及模拟转换是非常可靠的装置， 可以链接模拟传感器至不同的模拟设备。该LAC 范围范围：： 电压和电流回路输出可允许一个范围较广的过滤。偏移和增加设定适合任何工业应用。因为 激发AC 测压元件和电源电位隔离。该LAC 没有不良的影响和干扰并优于任何同类装置。 这些特点加上比率计的设计（包括附加可选模块）以确保高度精准及可靠性。附加的安全装 置以确保如果在任何一个测压元件或它的接头发生故障LAC 将自动故障保护。在安全鉴定 应用中尤为重要。 Analogue input: up to six load cells,(each ＞350W) may be connected. The low load cell supply voltage (2.5VAC), minimise warm-up errors. AC load cell supply (425Hz carrier), ratiometric voltage loop design and sense inputs allow long load cell cables ( ＞10m) to be used even in electrically hostile environments (2.5VAC), 模拟输出：模拟输出：相当于6 个测压元件(每个 ＞350W)可能连接。低的测压元件电压供给可能发生 模拟输出模拟输出：： 最小误差。AC 测压元件供应(425Hz 载体), 比率计电压回路设计和感应输入允许长的测压 元件电缆( ＞10m)可用于一个电气有害环境下(2.5VAC)。 Low pass filter: 64 steps of filter setting ranging from 0.25to 32 Hz can be selected. 低通滤波器：低通滤波器：在滤波器上可选设置范围从0.25 至32 Hz 的64 步。 低通滤波器低通滤波器：： Zero off-set: Adjustment of either positive and negative offsets(up to ±80%FS) can be made using a combination of DIL switches (32 steps) and a potentiometer (fine). 零偏移：零偏移：调节正反偏移量(相当于±80%FS)可结合DIL 开关(32 步)和一个分压计（优良） 零偏移零偏移：： 结合使用。 Gain: Can be set in 32 steps
