SCM7B Modules
SCM7B Isolated Process Control Signal Conditioning modules include a
complete selection of backpanels, DIN rail mounting accessories, interface
cables, and rack mounting hardware. Each SCM7B module provides a single
channel of isolated analog input or output. Various input modules accept analog
voltage or current signals from all types of field sensors and sources, filter, isolate,
amplify, linearize, and convert these input signals to high-level analog outputs
suitable for use in a process control system. Output modules accept high-level
analog voltage signals from a process control system, then buffer, isolate, filter,
and amplify before providing a current or voltage output to a field device.
