Detailed Description:
-
Compact Front-End Expansion: The signal board plugs directly into a dedicated slot on the front of the CPU or a signal module, requiring no additional rail width, maintaining a compact control cabinet layout. It provides great convenience for users needing to add a small number of I/O points late in a project.
-
Input Characteristics: Provides 2 independent analog input channels. Each channel can be configured for the following standard industrial signals:
-
Voltage Input: ±10 V
-
Current Input: 0 – 20 mA, 4 – 20 mA
-
-
High-Precision Conversion: The module offers sufficient accuracy with a 13-bit resolution, meeting the needs of most process measurement applications.
-
Flexible Addressing: The I/O addresses of the signal board are automatically assigned by the system and integrated into the CPU’s I/O system, allowing for easy configuration in TIA Portal.
-
Application Scenarios: Particularly suitable for space-constrained applications or situations requiring temporary addition of a few analog measurement points, such as connecting additional temperature transmitters, pressure sensors, or flow meters.
