Detailed Description:
-
Compact Front-End Expansion: The signal board plugs directly into a dedicated slot on the front of an S7-200 SMART CPU, requiring no additional rail width, maintaining a compact control cabinet layout. It provides great convenience for users needing to add analog output points late in a project or in space-constrained situations.
-
Output Characteristics: Provides 2 independent analog output channels. Each channel can be configured for the following industrial standard signals:
-
Voltage Output: ±10 V
-
Current Output: 0 – 20 mA, 4 – 20 mA
-
-
Basic Accuracy & Resolution: The module offers basic accuracy and resolution sufficient for most process control applications, such as providing a speed setpoint to a frequency converter or a control signal to a proportional valve.
-
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 STEP 7-Micro/WIN SMART software.
-
Application Scenarios: Particularly suitable for applications requiring the addition of a small number of analog control outputs in space-constrained environments. Examples include adding a speed output to an existing CPU for controlling a frequency converter, or connecting an analog display meter.
