Function

High-precision analog input: 8 differential input channels, supporting various voltage and current signals (±10V, ±5V, ±2.5V, 0-20mA, 4-20mA), 12-bit + sign bit resolution, suitable for high-precision measurement.

Flexible configuration: The input types and ranges can be configured through the TIA Portal software to adapt to the requirements of different sensors.

Photoelectric isolation: The input is isolated from the backplane bus, enhancing anti-interference capability and protecting the module and system.

Diagnostic function: Supports over-range and disconnection detection (4-20 mA mode), and provides real-time status monitoring through LED indication and TIA Portal.

Fast conversion: The conversion time for each channel is approximately 250 µs, supporting rapid signal acquisition and suitable for dynamic process monitoring.

Modular design: Seamlessly integrated with S7-1200 series cpus, easy to install and expand.

Compact size: Saves control cabinet space and is suitable for small-scale automation systems.

Application scenarios
