可以在显示屏上直接设定开关点，也可以通过外部PLC的4...20 mA信号输入来编程控制。
with the 3 key pads or optionally, with input 4...20 mA, from an external PLC over a 4...20 mA loop. As an option,
the process value can additionally be transmitted to the PLC (4...20 mA).
The connection of the 8400 to the process in the piping is made using standard fittings.
