SG-3011 Isolated Thermocouple Input Module

User’s Manual

Introduction

The SG-3011 is a thermocouple input signal conditioner. SG-3011 uses

microprocessor-controlled high-resolution 24-bit dual-slope,integrating A/D

converter to acquire thermocouple signal and cold junction compensation input.

Temperature measurement is handled by thermocouple linearization and cold

junction compensation function. The supported thermocouple types are J, K,

T, E, R, S, B, N, C, L, M,L2(DIN 43710).

The SG-3011 features optical isolation technique providing 3000Vdc isolation.

The power supply that drives the module`s input and output circuitry is

internally isolated,enabling SG-3011 to offer true channel - to - channel

isolation.

It’s easy to mount the SG-3011 on a standard DIN rail and can operate in

environment with wide temperature range.

Configuration

The terminal wiring for the SG-3011 is shown in Figure A. The SG-3011 uses a power input
range of 10~30Vdc.

Figures D and E show the switch positions used to configure the input and output range.
The I/O configuration switches are located inside the module and can be accessed by
removing the DIN-rail bracket covers by sliding them in the direction shown in Figure B.
