SCM7B40/41

Isolated Analog Voltage Input Modules, Wide Bandwidth

Description

Each SCM7B40/41 voltage input module accepts one channel of analog voltage

input which is filtered, isolated, amplified, and converted to a high level analog

voltage for output to the process control system.

These modules incorporate a five-pole filtering approach to maximize both time

and frequency response by taking advantage of both Thomson (Bessel) and

Butterworth characteristics. One pole of the filter is on the field side of the isolation

barrier; four are on the process control system side.

After the initial field-side filtering, the input signal is chopped by a proprietary

chopper circuit and transferred across the transformer isolation barrier,

suppressing transmission of common mode spikes and surges. The signal is

then reconstructed and filtered for process control system output.

Modules accept a wide 14 - 35VDC power supply range (+24VDC nominal).

Their compact packages (2.13"x1.705"x0.605" max) save space and are ideal

for high channel density applications. They are designed for easy DIN rail

mounting using any of the -DIN backpanels.
