Function

Mixed signal processing: Integrates 8 analog input channels and 2 analog output channels, eliminating the need for separate configuration of input/output modules, saving rack space and costs, and is suitable for "acquisition + control" integrated scenarios

Multi-signal compatibility: The input supports signals from various commonly used industrial sensors such as voltage, current, thermocouple, and thermal resistance, and the output supports voltage/current signals. It can be directly connected to sensors and actuators, adapting to complex industrial environments

High-precision data conversion: 16-bit high resolution and low error accuracy ensure the accuracy of analog signal acquisition and output, meeting the strict requirements for parameter accuracy in process control

Flexible parameter configuration: Through the Step7 software, the signal type, range, filter parameters, etc. of each channel can be independently configured without the need for hardware jumpers. It supports online modification and parameter backup

Signal filtering and anti-interference: Built-in digital filtering function, which can suppress electromagnetic interference in industrial sites and enhance signal stability; Supports disconnection detection (for thermal resistors/thermocouples), facilitating fault detection

Diagnosis and status feedback: It is equipped with diagnostic functions for power faults, channel faults, signal over-range, etc. Fault information is uploaded to the CPU in real time, and the status indicator light on the front of the module visually displays the working status

Application scenarios

In the field of process control: Parameter acquisition and closed-loop control of temperature, pressure, flow rate, liquid level, etc. in the chemical, petrochemical, and pharmaceutical industries

Manufacturing automation: Process parameter monitoring and actuator control of production line equipment

Energy management system: Collection of electrical parameters such as voltage, current and power in power plants and substations, as well as speed regulation of frequency converters and charging and discharging control of energy storage devices

Environmental monitoring and control: Temperature and humidity collection for central air conditioning systems + fan/water valve regulation, pressure difference/temperature and humidity collection in clean workshops and control of air conditioning units

Metallurgy and Building Materials: Temperature/pressure collection for blast furnaces in steel mills, temperature collection for kilns in cement plants + fuel supply regulation

Water treatment industry: Collection of water quality parameters such as dissolved oxygen, pH value, and turbidity in sewage treatment plants, as well as flow control of dosing pumps and speed adjustment of aeration fans
