The ABB+CMA126 is a DCS (Distributed Control System) PLC (Programmable Logic Controller) module likely designed for ABB’s Advant Master or Freelance DCS systems. Here’s what we can glean based on available resources and common functionalities:
Product Name: ABB CMA126 Analog Input Module
Product Description: Based on the naming convention and common functionalities within DCS/PLC systems, the CMA126 is likely an analog input module. This means it interfaces with sensors that provide continuous voltage or current signals representing process variables like temperature, pressure, flow, or level. The CMA126 converts these analog signals into digital data that the DCS system can understand and utilize for control purposes.
Product Parameters & Specifications:
Finding in-depth specifications online might be difficult due to potential obsolescence. Here’s what we can expect generally:
- Compatibility: The CMA126 would likely be designed for a specific ABB DCS system and might require other modules for complete functionality.
- Number of Analog Input Channels: A crucial parameter is the number of analog input channels the module can accommodate, allowing it to connect to multiple sensors.
- Analog Input Range: The voltage or current range measurable by the module would be important. Typical ranges might be 0-10V, 4-20mA, etc.
- Resolution: This refers to the smallest change in the analog signal that the CMA126 can distinguish and convert into digital data. Higher resolution provides more accurate measurements.
- Conversion Time: The time it takes for the module to convert an analog signal to digital data is a relevant specification. Faster conversion times are desirable for real-time process control.
