Current Output
Connections are made to current outputs A thru D as shown. Each current output is program-
mable as either 4 to 20 mADC or 0 to 20 mADC. Each output must be assigned to the desired
function (refer to Table 3-2, page 28, for details.) Terminal connections are made using TB10
through TB13 for current output A through D respectively. Connect positive lead (+) to
terminal 1 and the negative lead (-) to terminal 2. Current outputs will operate up to 650 ohms
maximum load.
FIGURE 2-13
Transmitter Power Supply Input
If the isolated 24 VDC regulated transmitter power supply has been specified, the connections
should be made as shown. Connections are made using TB3, terminal 1 is positive and
terminal 2 is negative. The power supply is capable of providing the power needed by as
many as 2 transmitters.
