Installation
Connection
For both the DI and DO modules, use 24–12 AWG (0.2–3.31 mm
2
) wire of suffi-
cient current capacity to connect to the digital input and output terminals for your
application.
The order of mapping for DO modules is the same as that for DI modules.
SEL-2245-42 AC Analog Input Module
The SEL-2245-42 AC Analog Input Module (see Figure 2.42) provides protec-
tion-class ac analog input (CT/PT) and can accept three voltage and three current
inputs. The module samples at 24 kHz and is 1 A or 5 A software-selectable.
Depending on the supported fixed topology, multiple CT/PT input modules can
function in each node. Some topologies only support one CT/PT module per
node. See Topologies on page 2.42 for more information on supported relay
topologies and their connections.
