假设24 V馈电是安全的，例如，根据
EN 60950（防触电）和UL 950。
3.如果24 V DC和
230 V AC，可以对所有馈线使用相同的24 V设备。
4.将24 V馈线上的0 V连接到地面。这有三个优点：
–提高了安全性。发生故障时，24 V馈电将不带电
0 V（24 V）和230 V相之间的连接或短路。
–24 V馈线上的瞬态连接到地面。
–24 V馈电与地面的关系没有高电平的风险。
这并不罕见，因为存在高静电。
下面是一个例子，解释了为什么安全的24 V DC馈电会被以下情况破坏
在较小的控制器中混合24 V继电器触点和230 V AC继电器触点。

AC符合EN 60950 If you use a power supply that meets safety standards and only feeds the
operator panel, there is no problem.
2. However, if you have a 24 V unit that also feeds other units, there is reason to
be cautious.
The operator panel does not have insulation that meets safety requirements in
the event of a potential short circuit between 230 V AC and r supply

assumed that the 24 V feed is secure, for example, SELV according to
EN 60950 (protection against electric shock) and UL 950.
3. If there is a substantial distance between the relay contacts for 24 V DC and
230 V AC, it is OK to use the same 24 V devices for all feeds.
4. Connect 0 V on the 24 V feed to the ground. This offers three advantages:
– Safety is increased. The 24 V feed will not be live in the event of a faulty
connection or short circuit between 0 V (24 V) and 230 V phase.
– Transients on the 24 V feed are connected to the ground.
– No risk that the 24 V feed is at a high level in relationship to the ground.
This is not unusual since there is high static electricity.
Here is an example that explains why a secure 24 V DC feed can be ruined by
mixing 24 V relay contacts with 230 V AC relay contacts in a smaller controller.
