Specifications
This chapter lists specifications for the SCC-8-8-2 baseboard
The specifications in this chapter are specific to the SCC-8-8-2 baseboard. Refer to the OEM user's guide or
SC-1608 Series data sheet posted on our website for OEM DAQ board specifications.
All specifications are subject to change without notice.
Typical for 25 °C unless otherwise specified.
Specifications in italic text are guaranteed by design.
Analog input
Table 1. Analog input CJC specifications
Parameter Specification
8B analog input module CJC
sensor
(Note 1) Vishay-Dale TFPT1206L1002DM
CJC control jumper J21-J28:
 Position 1-2: CJC enabled
 Position 2-3: CJC disabled (default)
Note 1: Each 8B analog input module location (CH0-CH7) includes a CJC sensor and three-pin header with
jumper control (J21-J28).
Analog output
Table 2. Analog output jumper control specifications
Parameter Specification
8B I/O module analog output
jumper control (J29 and J31)
(Note 2)  J29 position 1-2: No function (default)
 J29 position 2-3: Connects DAQ AOUT0 to DAQ analog input CH8 (J35 pin 13), or
converts 8B I/O location CH8 to an 8B input module location.
 J31 position 1-2: No function (default)
 J31 position 2-3: Connects DAQ AOUT1 to DAQ analog input CH9 (J35 pin 14), or
converts 8B I/O location CH9 to an 8B input module location.
8B I/O module voltage divider
jumper control (J30 and J32)
(Note 3) 2×4.99 kΩ resistor, 0.1% tolerance, 25 ppm
 J30 position 1-2: DAQ AOUT0 outputs ±10 V output range (default)
 J30 position 2-3: DAQ AOUT0 outputs ±5 V output range
 J32 position 1-2: DAQ AOUT1 outputs ±10V output range (default)
 J32 position 2-3: DAQ AOUT1 outputs ±5V output range
Note 2: Three-pin headers J29 and J31 can be configured to read the OEM DAQ board's analog output
control voltage at 8B I/O module locations with OEM DAQ board AIN CH8 and CH9 when using
the USB-1608GX-2AO-OEM. When using the E-1608-OEM, the AOUTx voltage can be read at the
J35 header connector (pins 25 and pins 27) using a voltmeter or other DAQ board.
When using a DAQ board that does not have analog output capability, such as the USB-1608G-
OEM and USB-1608GX-OEM, configuring headers J29 and J31 for position 2-3 converts 8B I/O
module locations CH8 and CH9 to an 8B input module location (for a total of 10 8B input locations).
Voltage input modules installed in CH8 and CH9 must be 2-wire types that don't require excitation
terminals.
