Isolated Analog Signal Conditioning Products S C M 5 B SCM5B48 Accelerometer Input Module Description The S B provides excitation to pie oelectric sensors with built in microelectronic amplifiers, commonly nown as I P®* or IEPE* or LIVM* sensors. The module provides a constant current excitation to the sensor, then isolates, filters, and amplifies the sensor output, yielding a high level analog voltage output (Figure 1). The excitation current, signal gain, and filter high pass and low pass cutoff fre uencies are field configurable through a set of slide switches. Features Six poles of signal filtering in the S B module result in greater than dB of normal mode re ection for signal fre uencies above the cutoff fre uency. One pole of filtering is on the field side of the isolation barrier for anti aliasing purposes and the remaining five pole programmable Bessel filter is located on the system side. High pass filtering is achieved through a second order passive filter, located on the field side. If desired, the output switch can be turned on continuously by simply connecting pin , the Read nable pin, to I O ommon, pin . • Input Protection to 240Vrms Continuous The SCM5B48 offers the option of setting the constant current source for sensor excitation to common values of 4mA or 9mA with a compliance voltage of D . Programmable gains of , and are selectable and the module offers a ± 10V output. The required supply level is +5VDC, ± 5% . To ensure protection of expensive data acquisition equipment, the SCM5B48 module signal inputs and sensor excitation outputs are protected against accidental connection of voltages up to 240Vrms. * ICP is a registered trademark of PCB Group Inc. * IEPE is Integrated Electronic Piezo-Electric * LIVM is Low Impedance Voltage Mode F i g u r e 1 : S C M 5 B 4 8 B l o ck • Interfaces to ICP®* or IEPE* or LIVM* Sensors • ± 5V or ± 10V Output Range • 1500Vrms Transformer Isolation • ANSI/IEEE C37.90.1 Transient Protection , , and . , , Programmable Gain , and . and H Programmable HP Filter mA or mA Programmable urrent xcitation • 100dB CMR • ± 0.2% Accuracy • ± 0.01% Linearity Low Drift with Ambient Temperature to SA Operating Temperature Range S ertified • CE Compliant • ATEX Compliance Pending • Mix and Match SCM5B Types on Backpanel D ia g r a m 3 8 ©1995-2017 Dataforth Corporation, All Rights Reserved H Programmable LP Filter For information call 800-444-7644 ISO9001:2008-Registered QMS Specifications Typical❇ at TA Module Input Type Range(1) Protection Continuous Transient Excitation Constant Current(2) Compliance Voltage Protection Continuous Transient Output Range Resistance Protection Gain Programmable(2) CMR (50/60Hz) Accuracy(3) Linearity Stability Offset Gain Output Noise, Gain=1 , BW= 20kHz Low Pass Filter Type Programmable(2) High Pass Filter Programmable(2) CMV (Input to Output) Continuous Transient NMR Power Supply Voltage Power Supply Current and D power SCM5B48 Accelerometer ± 10V Ordering Information Model Input Range(1) Output Range Bandwidth SCM5B48-01 SCM5B48-02 – 10V to +10V – 10V to +10V – 10V to +10V – 5V to +5V 2.5kHz to 20kHz(2) 2.5kHz to 20kHz(2) 240Vrms max ANSI/IEEE C37.90.1 4mA or 9mA, ± 10% 24V ± 10% 240Vrms max ANSI/IEEE C37.90.1 See Ordering Information Continuous Short to Ground 1, 10, 100 100dB ± 0.2% Span ± 0.01% Span ppm ppm rms Bessel 2.5kHz, 5kHz, 10kHz, 20kHz DC, 0.2Hz, 10Hz 1500Vrms max ANSI/IEEE C37.90.1 db per Decade above cutoff fre uency Power Supply Sensitivity +5VDC ± 5% 110mA typical (9mA excitation) 70mA typical (4mA excitation) ± 600µ V/% RTI (4) Mechanical Dimensions (h)(w)(d) 2.28” x 2.26” x 0.6” (58mm x 57mm x 15mm) Environmental Operating Temperature Range Storage Temperature Range S C M 5 B Figure S B Side Label to to NOTES: ❇ ontact factory or your local Dataforth sales office for maximum values.
