IC693ACC350

IC693ACC350暖通空调负荷（压缩机、风扇、气体阀等）关断期间，信号继电器的触点断开。当触点打开时，整流桥的端子看到HVAC变压器的电压为24VAC，并将交流电源转为直流电源，如先前所述。由此得到的直流电压被用于驱动恒温器或子电路。

暖通空调负荷导通期间，信号继电器的触点闭合。当触点关闭时，跨过整流桥端子的电压降到零。这样无需将24VAC用作电源，因此恒温器的电池电源控制电路。操作机电继电器所需电流的范围从几十到几百毫安不等，它可对电池寿命产生显著影响。

如果有种方法无需要使用恒温器的电池即可驱动继电器，情况将会怎样？电池寿命会增加，更换频率将进一步降低。一种方法是在暖通空调负荷导通期间（信号继电器触点闭合），短暂打开继电器并为控制系统充电。相比功率继电器的关断时间，充电期间所需时间需要非常短，这样可激励功率继电器及其相应负荷。不幸的是，机电（信号）继电器由于其开关速度限制不太可能实现这一目标。触点移至期望位置花费的时间处在毫秒范围内，并将中断HVAC负荷运转。
