Introducing the SC-1608 Series
The SC-1608 Series is a family of products that integrate DAQ functionality, isolated analog signal
conditioning, and isolated digital I/O signal conditioning on one board. The SC-1608 Series includes the
following products:
SC-1608 Series Product Components
SC-1608-2AO-ENET SCC-8-8-2 baseboard and power supply, E-1608-OEM, cable, accessory kit
SC-1608X-2AO-USB SCC-8-8-2 baseboard and power supply, USB-1608GX-2AO-OEM, cable, accessory kit
SC-1608X-USB SCC-8-8-2 baseboard and power supply, USB-1608GX-OEM, cable, accessory kit
SC-1608-USB SCC-8-8-2 baseboard and power supply, USB-1608G-OEM, cable, accessory kit
You can install industry-standard 8B analog signal conditioning modules and solid state relay (SSR) digital I/O
modules onto the baseboard. The SC-1608 Series can be installed in a rack mount enclosure or used on a bench.
SCC-8-8-2 baseboard
The SCC-8-8-2 baseboard provides the following features:
 Connectors for mating with a USB-1608G-OEM Series board or E-1608-OEM board.
 Mounting locations for eight 8B analog input modules and two 8B analog input or output modules.
8B modules provide 500 V channel-to-channel isolated signal conditioning for voltage, thermocouples,
RTD, strain gauge, current and frequency type signals.
 Mounting locations for eight SSR digital I/O modules.
o SSR digital I/O modules are isolated relay control modules that sense AC/DC voltages from a field
source and respond with a digital output signal, or to switch and control AC/DC loads using a digital
signal. You set the module type for input or output, and the logic polarity to invert or non-invert.
 50-pin User I/O header connector.
o The 50-pin User I/O header connector is where all non-conditioned input and output signals are
available for user connections.
 Screw terminals to access all conditioned analog and digital signals.
The SCC-8-8-2 baseboard is powered with a supplied 12 volt, 30 watt external power supply. An alternate
power header is available to connect a user-supplied 12 VDC power supply.
Integrated DAQ Functionality
The USB-1608G-OEM Series board or E-1608-OEM mates directly onto the SCC-8-8-2 baseboard.
Unless a feature is applicable only to a specific SC-1608 Series product, this document refers to the USB-
1608G-OEM Series and E-1608-OEM board as OEM DAQ board.
USB-1608G-OEM Series
The USB-1608G-OEM Series includes the USB-1608GX-2AO-OEM, USB-1608GX-OEM, and
USB-1608G-OEM. These boards provide the following features:
 Eight differential (DIFF) or 16 single-ended (SE) analog input channels (SE mode is required for use with
8B analog I/O modules)
 Sample rates up to 500 kS/s aggregate
 Two analog output channels (USB-1608GX-2AO-OEM)
 Eight individually-configurable digital I/O channels
 Two counter channels (32-bit) that count TTL pulses
 One timer output channel (32-bit)
 Header connectors for mating with the SCC-8-8-2 baseboard
