Each B module provides power to a current transmitter, then isolates, filters, and amplifies the resulting process current input signal and provides an analog voltage output (Figure 1). Current to voltage conversion is accomplished internal to the module to ensure high accuracy. Features • +12VDC Loop Supply • Provides Isolation for Non-Isolated 2-Wire Transmitters • High-Level Voltage Outputs Signal filtering is accomplished with a pole filter optimi ed for time and frequency response which provides 60dB per decade of normal-mode re ection above H . • 1500Vrms Isolation A special input circuit on the 8B42 module provides protection against accidental connection of power-line voltages up to 40VAC. Clamp circuits on the I/O and power terminals protect against harmful transients. • 100dB CMR Isolation is provided by transformer coupling to suppress transmission of common mode spikes or surges. The module is powered from +5VDC, ± 5% . The modules are designed for installation in Class I, Division 2 hazardous locations and have a high level of immunity to environmental noise. • ANSI/IEEE C37.90.1 Transient Protection • Input Protection to 40VAC Continuous • 100Hz Bandwidth • ± 0.05% Accuracy • ± 0.02% Linearity Low Drift with Ambient Temperature • C-UL-US Listed • CE Compliant • ATEX Compliance Pending • Mix and Match Module Types on Backpanel F i g u r e 1 : 8 B 4 2 B l o ck D ia g r a m 1 2 4 ©1995-2017 Dataforth Corporation, All Rights Reserved For information call 800-444-7644 ISO9001:2008-Registered QMS SensorLex® 8B Isolated Analog Signal Conditioning Products Typical❇ at TA Module Input Range Input Resistance Normal Power Off Input Protection Continuous Transient Loop Supply Voltage Loop Supply Protection CMV, Input to Output Transient, Input to Output CMR (50Hz or 60Hz) NMR Accuracy(1) Linearity Stability Offset Gain Noise Output, 100kHz Bandwidth, – 3dB Response Time, 90% Span Output Range Output Protection Transient Power Supply Voltage Power Supply Current Power Supply Sensitivity Mechanical Dimensions (h)(w)(d) Environmental Operating Temperature Range Storage Temperature Range Relative Humidity Emissions EN61000-6-4 Radiated, Conducted Immunity EN61000-6-2 RF ESD, EFT and D power Ordering Information 8B42 4mA to 20mA Model Input Range Output Range 8B42-01 8B42-02 4mA to 20mA 4mA to 20mA 0V to +5V +1V to +5V 40VAC ANSI/IEEE C37.90.1 12VDC 40VAC 8 B Specifications 8 B 1500Vrms max ANSI/IEEE C37.90.1 100dB dB per Decade above H ± 0.05% Span ± 0.02% Span ppm ppm rms 100Hz 5ms 0V to +5V Continuous Short to Ground ANSI/IEEE C37.90.1 +5VDC ± 5% 140mA ± 200ppm/% 1.11” x 1.65” x 0.40” (28.1mm x 41.9mm x 10.2mm) to to 0 to 95% Noncondensing ISM, Group 1 Class A ISM, Group 1 Performance A ± 0.5% Span Error Performance B NOTES: ❇ ontact factory or your local Dataforth sales office for maximum values.
