Figure 2.11 Remote Relay Reset Signal Connection
A single switch contact can also be shared by multiple Temperature modules
wired in series as shown in Figure 2.12. When multiple modules are wired to a
single switch, only one 4-20 mA output channel is necessary to supply all the
modules
ATTENTION
The switch power supply is isolated, but shares common
with Channel 4 and Channel 5 4-20 mA outputs. Care
should be taken as to how these are grounded, if at all.
ATTENTION
The relay reset connections may be different for different
XM modules. Figure 2.12 applies only to the XM-361 and
XM-362 modules. Refer to the installation instructions for
the module for its terminal assignments.
IMPORTANT
The XM-360/361/362 relay reset signal is not compatible
with other XM module’s relay reset input. Use of a single
switch requires a multi-pole switch. Refer to the XM
Module User Manual for more information about the other
XM modules.
TIP
Up to 24 XM-361/362 modules can be wired in series in a
single loop.
