DIN Rail High-Voltage Switch with Digital Inputs
- 8 channels of power switching
- Support for 120 to 240 Volt 50/60 Hz lighting and motor loads
- 8 voltage-driven isolated digital inputs
- Override input
The Crestron® DIN-8SW8-I is an 8-channel lighting control module designed to support non-dimmable lighting and fan switching. The module features eight isolated digital inputs, allowing standard momentary switches to trigger events with or without a control system. A single model supports both 120V and 220-240V applications. Each channel handles incandescent loads up to 10A, fluorescent loads up to 5A, and 1/2 HP motor loads[1].
Override Input
Override inputs are provided to allow an external contact closure to momentarily override the control system program and set each channel output to its override preset level. Levels can be adjusted and saved locally from the front panel or remotely via software.
Isolated Local Inputs
The DIN-8SW8-I provides eight isolated local inputs, allowing momentary pushbutton keypads to be used. By default, a momentary voltage applied to each input will cause the associated relay to toggle on/off. The attached Crestron control system can override this behavior and create eight general-purpose inputs. In this mode, pushbutton keypads can be programmed to provide customized functionality.
DIN Rail Installation
The DIN-8SW8-I is designed to snap onto a standard DIN rail for installation in a wall mount enclosure. Wiring connections are made using screw terminals positioned along the bottom, clearly accessible from the front for easy installation and servicing. All setup controls and indicators are positioned on the center front panel. When installed in an enclosure utilizing 45 mm cutouts, the DIN-8SW8-I's front panel stays accessible while the connections are concealed.
Cresnet® Wired Communications
The DIN-8SW8-I communicates with a Crestron® Control System using the Cresnet control network. A pair of Cresnet ports is provided on the DIN-8SW8-I, allowing for easy daisy-chaining of several DIN Rail Series automation control modules.
