Connecting the 4-20 mA Outputs
The XM-361 and XM-362 include six 4-20 mA output channels into a
maximum load of 600 ohms each. The 4-20 mA outputs are arranged into two
isolated banks of three outputs each. Each bank of 4-20 mA outputs is
electrically isolated from the other bank and from circuit power and ground.
The isolation provided is up to 250 V.
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 57 for a description of the 4-20 mA parameters.
Wire the 4-20 mA outputs to the terminal base unit as shown in Figure 2.9 and
Figure 2.10.
IMPORTANT
A Class 2 circuit can be provided by use of an NEC Class 2
rated power supply, or by using a SELV or PELV rated
power supply with a 5 Amp current limiting fuse installed
before the XM module(s).
IMPORTANT
24Vdc needs to be wired to terminal 37 (+24 V In) to
provide power to the device and other XM modules linked
to the wired terminal base via the side connector.
ATTENTION
The power connections are different for different XM
modules. Refer to the installation instructions for your
specific XM module for complete wiring information.
ATTENTION
The 4-20 mA output shields must be grounded at a single
point. It is recommended that where possible the cable
shield be grounded at the equipment wired to the 4-20 mA
output and not at the XM terminal base.
