SEL-400 Series Relays Instruction Manual Date Code 20171006
Remote Data Acquisition
Time-Domain Link (TiDL)
The SEL-2244-5 Fast High-Current Digital Output Module (see Figure 19.6)
consists of ten fast, high-current output contacts. The TiDL system can map as
many as 48 DO points to the relay. For more information on DO mapping, refer
to Section 2: PC Software.
The SEL-2245-42 AC Analog Input Module (see Figure 19.7) 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 the supported topologies in Section 2: Installation in the product-spe-
cific instruction manual for more information.
