Product Description P/N: ECX-420
Description
The Distech Controls ECX-420 is an I/O extension module designed to expand the input capacity of ECB-600 and ECL-600 Series programmable controllers used in commercial HVAC and building automation systems. Operating from a 24 VAC/DC power supply, the module adds additional universal input points for monitoring sensors and field devices without requiring a separate controller. The ECX-420 provides a scalable solution for extending control systems in air handling units, chillers, boilers, cooling towers, and central plant applications.

Information About ECX-420
The ECX-420 is part of the Distech Controls ECX-400 Series of extendible I/O modules developed for use with ECB-600 and ECL-600 Series BACnet and LONWORKS controllers. It features twelve universal hardware inputs that accept multiple signal types, including voltage, current, thermistor, resistance, dry contact, and pulse inputs for flexible field integration. The module communicates with its host controller over an integrated RS-485 expansion bus and is powered from a 24 VAC/DC Class 2 supply for dependable operation. Designed for commercial HVAC automation, the ECX-420 allows system designers to expand controller capacity while maintaining a compact, modular installation.
Key Features:
- Universal Input Expansion: Adds twelve configurable universal inputs to compatible controllers.
- ECX-400 Series Design: Integrates with ECB-600 and ECL-600 Series controllers.
- Multiple Input Types: Supports voltage, current, thermistor, resistance, digital contact, and pulse inputs.
- RS-485 Expansion Bus: Provides reliable communication with the host controller.
- 24 VAC/DC Operation: Powered by a Class 2, 24 VAC/DC supply for commercial installations.
- Modular Installation: Expands controller capacity without replacing the primary controller.
- Commercial HVAC Compatibility: Suitable for air handling units, boilers, chillers, cooling towers, and plant equipment.
- Rugged Industrial Design: Built for long-term operation in demanding building automation environments.
The ECX-420 delivers the reliability and precision required for expanding commercial HVAC building automation and equipment monitoring systems.
