1X00781H01L 输出模块的功率放大元件有驱动直流负载的大功率晶体管和场效应管

1X00781H01L输出模块的功率放大元件有驱动直流负载的大功率晶体管和场效应管、驱动交流负载的双向晶闸管，以及既可以驱动交流负载又可以驱动直流负载的小型继电器。输出电流的典型值为0.3～2A，负载电源由外部现场提供。1X00781H01L内部电路使继电器的线圈通电，1X00781H01L的常开触点闭合，使外部负载得电工作。继电器同时起隔离和功率放大作用，每一路只给用户提供一对常开触点。1X00781H01L与触点并联的RC电路和压敏电阻用来消除触点断开时产生的屯弧，以减轻它对CPU的干扰。

The power amplifier element of the 1X00781H01L output module has a high-power transistor and field effect tube to drive the DC load, a bidirectional thyristor to drive the AC load, and a small relay to drive both the AC load and the DC load. The typical value of the output current is 0.3 to 2A, and the load power is provided by the external field. The 1X00781H01L internal circuit energizes the coil of the relay, and the normally open contact of 1X00781H01L is closed to enable the external load to work. The relay acts as both isolation and power amplification, and provides the user with only a pair of normally open contacts for each route. The 1X00781H01L RC circuit in parallel with the contact and the varistor are used to eliminate the arc generated when the contact is broken to reduce its interference with the CPU.
