Hey everyone!
I have to install 4 new gas detectors (MSA x cell sensor) those are three wire devices (24+,24-,Signal)and to be added directly to DCS without a gas detector panel.
DCS is of yokogawa centum with io card aai135h00.Can I do it directly to DCS by sharing power supply common and signal.
Does this affect 4-20mA signal if we make it common.Also detectors are having a current of 300mA.
Is there any interface terminal board to do this?
