SCM7B Series
Isolated Process Control Signal Conditioning Products
SCM7B MODULES
Process Control Signal ConditioningEach Dataforth 7B module provides a single channel of isolated analog input or output.
  • Input modules accept analog voltage or current signals from all types of field sensors and sources; they filter, isolate, amplify, linearize, and convert the input signals to high-level analog outputs for use in process control systems
  • Output modules accept high-level analog voltage signals from a process control system, then buffer, isolate, filter, and amplify them before providing current or voltage output to field devices


All 7B modules are CSA C/US certified and CE and ATEX compliant.

Accessories include a complete selection of backpanels, DIN rail mounting options, interface cables, mounting racks, power supplies, and other accessory items.
CUSTOM SIGNAL CONDITIONING
Custom modules are available: consult factory for minimum quantity and pricing details on custom input ranges, output ranges, bandwidth, and other key parameters.
