007303010 Schneider TAC Xenta 491 Analog Output Module 8 x 0-10V DC Channels 24V AC Supply for Xenta 300

The TAC Xenta 491 analog output module (007303010) is part of Schneider Electric's building control generation that predates SpaceLogic and remains widely used across extensive installed systems. This module expands the analog output capacity of Xenta 300 or Xenta 401 controllers, providing essential additional channels when plant rooms expand with extra valves, dampers, and variable speed drives.

It features eight outputs, each delivering 0 to 10 V DC command signals with approximately 2 mA drive capability and short circuit protection - the standard interface for electric modulating valve and damper actuators. The module operates from the panel's 24 V AC supply, integrating seamlessly with existing controller transformers without requiring additional power supplies.

The module extends the host controller's output range without requiring separate addressing or network configuration. Engineering tools recognize the additional channels as part of the same device.

This module is designed exclusively for legacy plant rooms using Xenta 300 and Xenta 401 controllers, primarily serving spares and replacement needs rather than new installations.

Typical Applications:

• Expanding analog outputs when buildings add chillers, boilers, or air handling units
• Controlling electric valve and damper actuators
• Providing variable speed drive references for pumps and fans
• Supporting staged migrations to SpaceLogic while maintaining existing plant operations

The module enables strategic migration planning for sites that cannot accommodate simultaneous downtime across all mechanical plant systems.
