70年代中期以前的发展
20世纪，自动化科学技术的建立以及工业的发展，逐渐形成了自动化仪表工业。50年代以前，PID调节已很流行，但集检测、调节、执行功能于一体的基地式仪表仍为主流热工仪表。功能分离、信号传输、中央控制室集中显示操作，这种可应用于多个行业的通用性强的自动化仪表模式还在酝酿之中。
60年代，以电子管为基础的DDZ－I型电动单元组合仪表，被以晶体管分立元件为基础的DDZ-II型电动单元组合仪表取代。这是面向石油、化工、冶金、电力、建材等行业，以温度、压力、流量、液位为主要控制参数的整套工业自动化仪表。这个时期由于生产设备的大型化，已经有了中央控制室，基地式仪表的操作方式逐步被取代，但各单元仪表之间的连络信号还不统一，以直流0～10mA的电流信号应用较广。
70年代，一机部组织了DDZ－Ill型仪表的统一设计工作。DDZ-III型是在线性集成电路（运算放大器）技术、国际统一信号、本质安全防爆等技术的基础上发展起来的，与此同时，组装式仪表装置也在兴起。
60年代末70年代初，国际电工委员会IEC规定了国际统一信号为直流4～20mA，直流l～5V为辅助信号。即以4～2（ADC为传输信号，以1～5VDC为接收信号。这个国际统一信号在当时执行起来，基本没有多大阻力，原因是其技术先进、切实可行，而且原来的制造厂和用户都迫切希望有统一的信号制。
DDZ－III型仪表总体设计时，为了顺应500万吨／年原油处理量的大型炼油厂的自控系统的要求，一是系统要求本质安全防爆，二是要考虑现场仪表与中控室距离较远（约500米以内）。在符合国际统一信号的基础上，选用24VDC统一供电和两线制变送器及安全栅的方案。当时线性集成电路和晶体管的水平能做到在24VDC供电条件下，控制室仪表外接导线电阻与两线制变送器内阻或执行器内阻串联，可具有恒流性能。4mA是为了保证两线制变送器放大器工作点必要的供电而设的。在要求防爆的场所，也能够承受24VDC、20mADC或比它稍高的电量，所以能满足上述两项要求。
