Series 100 Plus Option Board Analog Output switch settings

The Series 100 Plus Option Board provides two 4-20 mA analog output signals that are hardware 
configurable to either sink or source current as described in 

 and 

 below 

and in Daniel drawing DE-21056 (

). 

Full HART® functionality is provided so that any commercially available HART® transmitter 
which meets the specifications of the HART® Communications Foundation can be connected to 
the Daniel® Ultrasonic Gas Flow Meter.

If the analog output is configured for ‘source’ mode (i.e., powered by the meter), then it  
must be at the bottom of the loop (stack). The HART® output cannot be multi-dropped 
when configured for source mode.
