SG-3013 User’s Manual
Isolated RTD Input Module
Introduction
The SG-3013 is a RTD input signal conditioning module to transform RTD input to voltage
or current output. SG-3013 uses a microprocessor-based transducer, which integrating two
high resolution ADCs and an MCU, to acquire the RTD signal. The supported RTD types
are Pt100 , Pt1000 , Ni 120 , Cu100 ,and Cu1000.
The SG-3013 supports 1000 V
DC
isolation. The power supply that drives the module`s input
and output circuitry is internally isolated.
It’s easy to mount the SG-3013 on a standard DIN rail and can operate in environment with
wide temperature range.
