JSB— 2 3半导体计时器是专供X线机的配套产品 ,该计时器有两套RC延时电路 ,即主控电器和辅控电路。主控电路调整定时共 2 3档 (0 0 4s~6 2s) ;辅控电路对主控电路实行分级保护。当主控电路失灵时 ,对执行继电器J失去控制 ,辅控电路可以在分级限定的时间内使执行继电器J释放
The JSB-23 semiconductor timer is an accessory product for X-ray machines. The timer has two sets of RC delay circuits, namely master control and auxiliary control circuits. The main control circuit adjusts the timing to a total of 23 files (0 0 4s to 6 2s); the auxiliary control circuit implements hierarchical protection for the main control circuit. When the main control circuit malfunctions, the control of the relay J is lost, and the auxiliary control circuit can release the execution relay J within the grading time limit.
