SCM7B33 - Isolated Process Current/Voltage Input Modules

This page provides the datasheet information for the SCM7B33, a member of the SCM7B32 Isolated Process Current/Voltage Input Modules family.

Description

The SCM7B32 current input modules accept input signals in the 4-20mA or 0-20mA ranges from the field and provide a high-level output to the process control system (Figure 1).

Current to voltage conversion occurs internal to the module, which is factory calibrated to ensure the highest accuracy.

Features

Isolated Process Control Signal Conditioning Products SCM7B SCM7B32/33 Isolated Process Current/V oltage Input Modules Description The SCM7B32 current input modules accept input signals in the 4-20mA or 0-20mA ranges from the field and provide a high-level output to the process control system (Figure 1). Current to voltage conversion occurs internal to the module, which is factory calibrated to ensure the highest accuracy. SCM7B33 voltage input modules accept input signals in the +1V to +5V or 0 to +5V ranges from the field and provide a high-level output to the process control system. As an alternative, the SCM7B33 can be used with an external 250Ω resistor (Dataforth SCM7BXR1 or equivalent), to accept input signals in the 4-20mA or 0-20mA ranges.
