***的电气性能
两线运行功率是直接从4到20 mA回路获得，不需要单独的输入功率。这简化了现场布线和消除电力线路噪声拾取的可能性。
隔离1500 V RMS（2100分）
这非常高的CMV评级从输入到输出的情况下或消除电气接地回路的信号源和接收机之间的可能性。它还提供了对电气***接收机高度的保护，如信号源和一个交流电源线之间的意外接触。
量程比
调节比为零***除以跨度。异常高的10:1的量程比可能与tx1500系列表明，宽零偏移可以联合窄信号跨在高增益的闭环控制。信号跨度也可以大批量操作控制，在很宽的范围内的信号水平可能在整个批处理周期中。
高过压保护
120伏的电压可以被施加在输入或输出引线1分钟在所有型号的热电偶输入电压或情况。反400分的极性，可以应用于输出引线下去。这些异常高电压等级NMV进一步防止可能的电气故障和接线错误。
