Overview

The IMDSI13, IMDSI14, and IMDSI22 Digital Input Modules are designed to provide 16 individual digital signals to the Symphony Enterprise Management and Control System for processing and monitoring. These modules serve as an interface between field devices and the control system.

Typical devices supplying digital signals include contact closures or switches. The control functions are managed by the controller, while the I/O modules handle the system’s inputs and outputs.

There are three variations of the DSI modules:

• IMDSI13: Accepts 24 VDC inputs.
• IMDSI14: Accepts 48 VDC inputs.
• IMDSI22: Supports multiple input types, including 120 VAC, 24 VDC, 48 VDC, or 125 VDC.

Each module allows seamless integration of field signals into the control system for efficient process management.
