(1)温度：PLC要求环境温度在0～55℃，安装时不能放在发热量大的元件下面，四周通风散热的空间应足够大。

(2)湿度：为了保证PLC的绝缘性能，空气的相对湿度应小于85％(无凝露)。

(3)震动：应使PLC远离强烈的震动源，防止振动频率为10～55 Hz的频繁或连续振动。当使用环境不可避免震动时，必须采取减震措施，如采用减震胶。

(4)空气：避免有腐蚀和易燃的气体，例如化学的酸碱等。对于空气中有较多粉尘或腐蚀性气体的环境，可将PLC安装在封闭性较好的控制室或控制柜中。例如电厂的干排渣、干除灰等，在基建后期增加了封闭小屋。

(5)电源：PLC对于电源线带来的干扰具有一定的抵制能力。在可靠性要求很高或电源干扰特别严重的环境中，可以安装一台带屏蔽层的隔离变压器，以减少设备与地之间的干扰。一般PLC都由直流24 V输出提供给输入端，当输入端使用外接直流电源时，应选用直流稳压电源。因为普通的整流滤波电源，由于纹波的影响，容易使PLC接收到错误信息。
