Functions

Multi-signal Compatibility: Flexibly adapts to voltage and current analog sensors, enabling direct connection of detection signals for temperature, pressure, etc., without additional conversion devices.

High-precision Acquisition: 12-bit resolution combined with low error characteristics ensures accurate conversion of weak signals in industrial fields, meeting the data precision requirements of closed-loop control.

Fast Response: Microsecond-level conversion speed can capture dynamic signal changes in real time, suitable for monitoring rapidly fluctuating parameters such as flow and liquid level.

Diagnosis and Indication: LED indicators display power, module, and channel status; supports PLC system diagnosis for quick troubleshooting of wiring or sensor faults.

Easy Expansion: Seamlessly compatible with S7-200 SMART series CPUs, directly mountable via rail, enabling system expansion without complex configuration.

Application Scenarios

Process Control: In chemical, water treatment and other industries, collects analog signals such as pipeline pressure, liquid flow, and solution pH value to provide data support for PID regulation.

Manufacturing: Connects to temperature sensors (e.g., signals converted by thermocouples, thermal resistors via transmitters) and weighing sensors in production lines to monitor equipment operating temperature and material weight.

Environmental Monitoring: Used in smart buildings or factory workshops to collect environmental parameters such as temperature, humidity, and air quality, and link with air conditioning and ventilation systems for automatic adjustment.

Energy Management: Monitors electrical parameters such as voltage, current, and power in power and photovoltaic systems to realize energy consumption statistics and equipment protection.
