Crestron C2N-SDC-DC – Shade and Drape Controller, 24V DC

Product Overview

The Crestron C2N-SDC-DC is a 2-channel Shade and Drape Controller designed for controlling 24 Volt DC motorized shades, drapes, and other 2-wire bidirectional window treatments. It operates as a Cresnet® device, receiving commands from any Cresnet-capable Crestron control processor. The C2N-SDC-DC provides a cost-effective solution for integrators managing DC motor-driven window automation in residential and commercial projects.

Product Description

The C2N-SDC-DC features two independently controlled 24VDC outputs, each capable of driving a conventional two-wire bidirectional motorized shade or drape. Built-in timing and interlock logic prevent simultaneous up and down drive signals, protecting motors from damage during programming and setup. Front-panel pushbuttons allow for manual motor operation during installation without requiring a programming device. The unit mounts into a standard 4-inch square or 2-gang electrical box, making it compatible with common rough-in hardware available from any electrical supply house.

Frequently Asked Questions

What type of motors does the C2N-SDC-DC support?
It supports 24 Volt DC, 2-wire bidirectional motors. This is a different motor type from 3-wire 120VAC motors, which require the C2N-SDC instead.

Can the C2N-SDC-DC control two shades independently?
Yes. Each of the two output channels is independently controlled and can be programmed with separate timing, limits, and commands.

Does the C2N-SDC-DC require a separate power supply for the motors?
Yes. The motor outputs supply 24VDC drawn from the connected motor's own external power supply. The device itself draws power from the Cresnet bus (3 W).
