Bipolar Current Pulse Output (IAD) Modul

   Picture IAD       Picture IAD   

Baer Bipolar Current Outputs deliver a constant 24V DC, but with a polarity change with each meter pulse.

This provides what amounts to an extra power supply, that is usually used to supply power to other Bipolar Current Outputs from the same unit. This means that individual connection terminals from different Bipolar Current Outputs must be isolated from each other, even if other equipment is connected in-between these terminals. Any Bipolar Current Inputs that come afterwards, must be isolated.
