E Series Multifunction DAQ Accessories

SCXI High-Performance Signal Conditioning (see Figure 1)

SCXI is a modular high-performance signal conditioning platform that you use as a

front end to your E Series DAQ device. With the SCXI multiplexing architecture, you

can expand your analog inputs to 3,072 channels. Additionally, SCXI offers a variety of

modules for connecting to thermocouples, RTDs, strain gauge transducers, LVDT

position sensors, ICP-compatible accelerometers/microphones, thermistors, millivolt

inputs, voltage inputs up to 1000 V, current inputs (0-20mA), frequency inputs or

dynamic signals.

See page 385 for details on SCXI Signal Conditioning.

SCC Series – Modular Signal Conditioning

for Low-Channel Count Applications

(see Figure 2)

The SCC Series modular signal conditioning system consists of SCC modules that

plug into a low-proﬁle SC-2345 shielded carrier. SCC modules give you single or

dual-channel signal conditioning for up to 16 analog input channels and eight

digital I/O lines of your plug-in E Series DAQ device. The SCC Series offers signal

conditioning for a variety of inputs, including thermocouples, RTDs, strain gauges,

ICP-compatible accelerometers, accelerators, analog inputs requiring isolation,

high voltage (up to 100 V), current (0-20mA), and optically isolated digital I/O.

Lowpass ﬁltering and bread boarding modules are also available.

See page 461 for details on SCC Signal Conditioning.

Connector Blocks

BNC-2100 Series Connector Blocks (see Figure 3)

Shielded connector blocks with signal-labeled BNC connectors for easy connectivity of

your analog input, analog output, digital I/O and counter/timer signals to your E Series

device. The BNC-2110 and BNC-2120 work with all E Series devices. The BNC-2120

also provides a function generator, quadrature encoder, temperature reference,

thermocouple connector and LED so that you can test the functionality of your hardware.

The BNC-2115 has 24 BNC inputs for connecting to the extended I/O channels of our

100-pin E Series DAQ devices.

BNC-2090 Shielded BNC Adapter Chassis (see Figure 4)

Shielded, rack-mountable adapter with signal-labeled BNC connectors, spring

terminal blocks, and component locations for passive signal conditioning. Consists of

22 BNC connectors and 28 spring terminals to simplify connection to your analog,

digital, trigger and counter/timer signals. The BNC-2090 has silk-screened

component locations that you use to develop simple signal conditioning circuits. For

added ﬂexibility, you can connect any E Series DAQ device to the BNC-2090 from

the front or rear through dual 68-pin connectors.
