GE WESDAC D20 C 504-0002-13 Combination Module WESDACD20C

The WESDAC D20 C 504-0002-13, centered on a modular architecture, flexible I/O configuration, and high-reliability communication capabilities, is specifically designed for small-point data acquisition and control scenarios. It seamlessly adapts to key fields such as substation automation and industrial process control, meeting the real-time data processing and equipment control requirements in complex environments through hot-swappable maintenance, multi-protocol compatibility, and industrial-grade stable performance.

Core Product Highlights

1. Modular Design for Efficient Installation and MaintenanceComposed of the WESTERM D20 C (bottom wiring module) and WESDAC D20 C (top data processing module), it supports lossless hot swapping. Module testing, replacement, and debugging can be completed without disconnecting on-site wiring.All on-site wiring is terminated at the bottom WESTERM D20 C module. The removal and reinstallation of the top module will not interfere with wiring connections, significantly reducing maintenance downtime and improving equipment operation and maintenance efficiency.Equipped with a Local/Remote switch, it can directly turn off the relay coil power and take the module offline. The offline status signal is transmitted to the D20 main processor in real time as a pseudo-status for the host to read, facilitating status monitoring and fault diagnosis.
2. Full-Featured I/O Configuration for Diverse ScenariosThe basic configuration covers 16 digital inputs and 8 control outputs. Among them, the control outputs support instantaneous or dual-function trip/close modes, meeting the requirements of conventional discrete signal acquisition and equipment control.Flexible analog expansion options are available: 16 analog inputs, or a combination of 8 analog inputs + 8 analog outputs. The analog precision reaches ±0.05% (voltage) and ±0.1% (current), adapting to high-precision sensor signal acquisition and actuator control.Supports multi-level status wetting options of 12V, 24V, 48V, and 130V, which can be flexibly matched according to on-site power supply specifications and compatible with signal interfaces of industrial equipment from different brands and types.
3. High-Reliability Communication and Distributed ArchitectureCompatible with the DNP3 open communication protocol and GE's proprietary D.20 Link protocol. Among them, D.20 Link supports high-speed polling and responsive data transmission, meeting the low-latency communication requirements in real-time control scenarios.Equipped with two DB9 connectors, it supports D.20 Link daisy-chain connection. The communication signal and the power supply of the WESDAC D20 C module share the same cable assembly, greatly simplifying on-site wiring and reducing installation costs.Designed based on a distributed processing architecture, the I/O module can be deployed close to the main equipment being monitored and controlled, reducing signal transmission distance and attenuation, improving the real-time performance and accuracy of data acquisition, and reducing the load on the main processor.
4. Industrial-Grade Stable Performance for Harsh EnvironmentsEquipped with an 8-bit Freescale 68HC11 microprocessor, combined with a 2MHz clock frequency, it can efficiently process multi-channel I/O data and meet the computing needs in high-load scenarios.The storage configuration includes 24KB EPROM, 32KB static RAM, and 512-byte EEPROM. The sufficient storage capacity can ensure stable program operation and temporary data storage, avoiding data loss.The analog conversion resolution reaches 14 bits + sign bit, and the temperature coefficient is as low as +10ppm/°C. It can maintain high-precision data acquisition even in complex industrial temperature and humidity environments, adapting to harsh scenarios such as substations and chemical workshops.
