Key Features
Combines field wiring termination (WESTERM D20C) and data processing (WESDAC D20C) in one unit, simplifying system architecture. Supports 16 digital inputs, 8 control outputs, and optional analog I/O for versatile signal handling.
Equipped with Ethernet, RS‑232/485, and DB9 ports, enabling daisy‑chaining and seamless integration with PLCs, SCADA, and DCS systems. Supports multiple industrial protocols for interoperability with legacy and modern devices.
IP67‑rated housing withstands dust, moisture, and industrial contaminants. Operates reliably across -20°C to +60°C, withstanding vibration and electromagnetic interference. Industrial‑grade polymer housing ensures mechanical stability and electrical insulation.
Features high‑accuracy analog channels (±0.05% stability) and galvanic isolation on all I/O channels to prevent noise and signal degradation. Fast‑clock processor meets high‑speed data acquisition and control demands.
Clear labeling and screw‑terminal design reduce wiring errors and simplify maintenance. Local/Remote switch disables relay coil power for safe offline configuration. LED indicators provide real‑time status for power, communication, and I/O activity.
Application Scenarios
- Power Substation Automation: Controller interface for switchgear, transformers, and protection relays in transmission/distribution substations.
