| 20 mA Current Loop Submodule |
| The 20mA current loop submodule is a plug-in for the communication processors SSM-BG41, BG42 and BG43. |
| It is used for point to point or bus connection communication. It has 2 lines for current loop transmission and reception. |
| In bus operation the sub-module connects in a potential (voltage) free state, preventing any influence on the existing loops. |
