SMD Compact Size, Active High Precision Signal Conditioning Modules - TE-T Series Posted on September 20, 2019

MORNSUN released a signal conditioning module TE-T series, which can isolate and convert the micro-signal accurately by extra-excitation.


The TE-T signal conditioning modules are designed to accept an input signals of either 4~20mA or 0-5V. The PCB design and SMD compact size package, not only make the whole system more reliable but also make mass production more efficient.

MORNSUN not only applies the power IC to the TE-T series, but also pre-packages the transformer, which further enhances the integration and reliability of the product.

Applications:

Widely used in applications of instrumentation, industrial control, petrochemical, power monitoring.
A typical application: Flowmeter


General application block diagram:


In above figure, Sin1 to Sin4 are external input voltage signals, A0 to A1 are strobe signals, and Signal out is an external input signal received by the control system. In the circuit, the optocoupler realizes the isolated transmission of the strobe signal, the TE-T series realizes the isolated transmission of the signal and the isolated power supply, and the multi-channel signal strobe chip 4052 realizes the selective transmission of the multiplexed signal.


Feature:
Two-port isolation (signal input and signal output)
