Multi-Channel Weighing Acquisition Module Specification

Model: SJ101T2_CH2 / CH4 / CH8 / CH10 / CH12 | Category: Multi-Channel Industrial Weighing Acquisition Module

Product Overview

The Multi-Channel Weighing Acquisition Module is an industrial-grade signal acquisition device designed for multi-point, multi-weight-level synchronous monitoring requirements. It offers various channel configurations (2/4/8/10/12), with each channel independently configurable without interference, and supports daisy-chaining of multiple modules. Through dual interfaces (RS485+RS232) and the standard MODBUS-RTU protocol, it enables efficient and flexible construction of large-scale weighing monitoring networks ranging from simple stations to complex distributed systems. It is an ideal choice for applications such as smart warehousing and production line monitoring.

Core Advantages: Multi-channel options for flexible configuration; Independent channels adapting to mixed scenarios; Efficient communication with single-command multi-channel data reading; Supports daisy-chaining for easy expansion; Rail mounting for convenient deployment.
