MegaTron Quick Steps 4-20mA Input Programming Step 28: Next you may need to assign additional Activators or Disablers for a relay. For example a relay with a Main Action of a mA INPUT set point may need to have a Disabler for a no flow alarm since this is not an automatic action for mA inputs. From the Relay Setup screen select Disabler 1 (Button 6) to go to the next screen RELAY 5 SETUP MAIN ACTION - OFF ACTIVATOR 2 ACTIVATOR 3 ACTIVATOR 4 DISABLE 1 DISABLE 2 DISABLE 3 DISABLE 4 00 - DAILY MAX Step 29: Select the action to disable relay using the Arrow buttons.

4-20mA output (sometimes called 4-20mA analog output since the output current is an "analog" of the measurement), then the transmitter is built into the sensor or meter. If it doesn't, you will need to add an external transmitter (such as Seametrics AO55) to convert the flow sensor pulse output to a 4-20mA current.

Academic writing is cautious, because many things are uncertain. When we put forward an argument, point of view or claim, we know that it can probably be contested and that not everybody would necessarily agree with it. We use words and phrases that express lack of certainty, such as: Appears to Tends to Seems to May indicate Might In some .
