General Electric WESDAC D20A SBA0009-00 is structured as a distributed analog input solution within the D20 RTU platform, combining field termination and signal processing through WESTERM D20 A and WESDAC D20 A modules. General Electric WESDAC D20A SBA0009-00 collects up to 32 analog inputs from field devices and converts them into digital data for transmission to the main D20 processor. The use of an 8-bit Freescale 68HC11 MPU enables stable onboard processing and efficient data handling. This architecture allows General Electric WESDAC D20A SBA0009-00 to operate close to field equipment while maintaining centralized system communication.
In practical industrial deployment, General Electric WESDAC D20A SBA0009-00 supports multiple input configurations, including voltage ranges of 1 V, 5 V, and 10 V, as well as current inputs processed through shunt resistors. General Electric WESDAC D20A SBA0009-00 also allows each input to be adapted through individual modules, making it suitable for mixed signal environments. A wetting source is provided for current loop inputs, improving compatibility with industrial transmitters. These capabilities enable General Electric WESDAC D20A SBA0009-00 to handle complex monitoring tasks in utility and process control systems.
From a communication and system integration perspective, General Electric WESDAC D20A SBA0009-00 connects to the D20 main processor through the D.20 Link using DB-9 interfaces. The module supports both DNP3 and HDLC protocols, ensuring reliable data transmission in distributed architectures. Maintenance and diagnostics can be performed via a 9600 baud RS-232 port, allowing engineers to access module status and input data in real time. General Electric WESDAC D20A SBA0009-00 is designed for flexible deployment in remote terminal unit systems where reliability and scalable I/O expansion are required.
The WESDAC D20A SBA0009-00 General Electric Analog Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
