SC-1608-2AO-ENET
Figure 3 shows the functionality provided by a SC-1608-2AO-ENET with analog I/O 8B modules and digital
I/O SSR modules installed.
Figure 3. SC-1608-2AO-ENET functionality
The E-1608-OEM receives power from the included external supply when the baseboard is powered on. When
connected to the baseboard, the E-1608-OEM power header connector (
W1 on the OEM DAQ board) mates
with the +5 V power header connector ( J37 ) on the baseboard. No additional supply is required.
Compatible modules
When using the SC-1608X-2AO-USB, SC-1608X-USB, SC-1608-USB, the total current available for 8B
analog I/O modules and SSR digital I/O modules is 1612 mA, maximum. When using the SC-1608-2AO-
ENET, the total current available for 8B analog I/O modules and SSR digital I/O modules is 1292 mA,
maximum. Keep these values in mind when installing modules.
SSR digital I/O control modules
SSR digital I/O modules are solid state relay control modules that provide 4000 Vrms optical isolation. Digital
input modules sense AC/DC voltages from field devices and convert them to digital TTL signals. Digital output
modules use TTL signals to switch and control AC/DC loads.
The baseboard has eight locations for single channel solid state relay modules. The input/output type is
configured with onboard switch
SW2 . The polarity is configured with onboard jumper W1 . The table below lists
the input and output modules that you can install.
