Isolated Analog Signal Conditioning Products S C M 5 B SCM5B30/31 Analog Voltage Input Modules, Narrow Bandwidth Description Each SCM5B30 and SCM5B31 voltage input module provides a single channel of analog input which is filtered, isolated, amplified, and converted to a high-level analog voltage output (Figure 1). This voltage output is logic-switch controlled, allowing these modules to share a common analog bus without the re uirement of external multiplexers. Features • Accepts Millivolt and Voltage Level Signals • High-Level Voltage Outputs The SCM5B modules are designed with a completely isolated computer side circuit which can be oated to from Power ommon, pin . This complete isolation means that no connection is re uired between I O Common and Power Common for proper operation of the output switch. If desired, the output switch can be turned on continuously by simply connecting pin , the Read nable pin, to I O ommon, pin . • 1500Vrms Transformer Isolation Signal filtering is accomplished with a six pole filter which provides dB of normal-mode rejection at 60Hz and 90dB at 50Hz. Two poles of this filter are on the field side of the isolation barrier, and the other four are on the computer side. • ± 0.03% Accuracy After the initial field side filtering, the input signal is chopped by a proprietary chopper circuit. Isolation is provided by transformer coupling, again using a proprietary technique to suppress transmission of common mode spikes or surges. The module is powered from +5VDC, ± 5%. • ANSI/IEEE C37.90.1 Transient Protection • Input Protected to 240VAC Continuous • 160dB CMR • 95dB NMR at 60Hz, 90dB at 50Hz • ± 0.005% Linearity Drift SA S ertified • CE and ATEX Compliant • Mix and Match SCM5B Types on Backpanel A special input circuit on the SCM5B30 and SCM5B31 modules provides protection against accidental connection of power-line voltages up to 240VAC.
