1715-C2 Expansion Cable
A 2 m (6.56 ft) expansion cable is available to connect I/O modules to field
devices, and to allow for space restrictions within the enclosure of the system.
IMPORTANT
The dual termination assembly does this by supporting inter-
module communication for current sync operation and by routing
the channel outputs from two 8-channel analog output modules
in parallel to 8 field devices. Therefore, each field device
receives a current source from a channel on each of two
modules. So if one module fails, or one or more channels fail on a
module, the outputs from the second module continues to supply
the field devices.
