SC-1608 Series User's Guide Introducing the SC-1608 Series

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.
