Connecting the 4-20 mA Outputs
The module includes an isolated 4-20 mA per channel output into a maximum
load of 300 ohms. The measurements that the 4-20 mA output tracks and the
signal levels that correspond to the 4 mA and 20 mA are configurable. Refer
to 4-20 mA Output Parameters on page 68 for details.
Wire the 4-20 mA outputs to the terminal base unit as shown in Figure 2.31.
ATTENTION
The Switch Input circuits are functionally isolated from
other circuits. It is recommended that the Switch RTN
signal be grounded at a signal point. Connect the Switch
RTN signal to the XM terminal base (Chassis terminal) or
directly to the DIN rail, or ground the signal at the switch
or other equipment that is wired to the switch.
