As a critical component in centralized Crestron lighting ecosystems, it delivers robust switching capabilities for a wide variety of high-voltage loads, including modern LED fixtures, fluorescent ballasts, and small motor loads (such as exhaust fans or motorized screens). What sets the \u003cstrong\u003e\"I\" version\u003c\/strong\u003e apart from the standard DIN-8SW8 is the inclusion of \u003cstrong\u003e8 isolated digital inputs\u003c\/strong\u003e. These inputs allow integrators to wire standard wall switches or sensors directly to the module. This not only expands the system's sensor capacity but also enables local, fail-safe operation of the relays if Cresnet communication is ever interrupted. Operating on the standard 24VDC Cresnet bus, its 9M wide form factor maximizes control density within standard automation enclosures.\u003c\/p\u003e\n\n    \u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n    \u003cdiv style=\"overflow-x: auto;\"\u003e\n        \u003ctable class=\"koeed-table\"\u003e\n            \u003cthead\u003e\n                \u003ctr\u003e\n                    \u003cth\u003eSpecification Category\u003c\/th\u003e\n                    \u003cth\u003eTechnical Details\u003c\/th\u003e\n                \u003c\/tr\u003e\n            \u003c\/thead\u003e\n            \u003ctbody\u003e\n                \u003ctr\u003e\n                    \u003ctd\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n                    \u003ctd\u003eCrestron Electronics\u003c\/td\u003e\n                \u003c\/tr\u003e\n                \u003ctr\u003e\n                    \u003ctd\u003e\u003cstrong\u003eModel Number\u003c\/strong\u003e\u003c\/td\u003e\n                    \u003ctd\u003eDIN-8SW8-I\u003c\/td\u003e\n                \u003c\/tr\u003e\n                \u003ctr\u003e\n                    \u003ctd\u003e\u003cstrong\u003eLoad Channels\u003c\/strong\u003e\u003c\/td\u003e\n                    \u003ctd\u003e8 x SPST normally open (N.O.) relays, independent line inputs\u003c\/td\u003e\n                \u003c\/tr\u003e\n                \u003ctr\u003e\n                    \u003ctd\u003e\u003cstrong\u003eMax Load Rating (Per Channel)\u003c\/strong\u003e\u003c\/td\u003e\n                    \u003ctd\u003e10A @ 120-240V AC; 5A @ 277V AC; 0.5 HP @ 120-240V AC\u003c\/td\u003e\n                \u003c\/tr\u003e\n                \u003ctr\u003e\n                    \u003ctd\u003e\u003cstrong\u003eSupported Load Types\u003c\/strong\u003e\u003c\/td\u003e\n                    \u003ctd\u003eIncandescent, LED, MLV, ELV, Fluorescent, Motors\u003c\/td\u003e\n                \u003c\/tr\u003e\n                \u003ctr\u003e\n                    \u003ctd\u003e\u003cstrong\u003eDigital Inputs\u003c\/strong\u003e\u003c\/td\u003e\n                    \u003ctd\u003e8 isolated inputs; supports dry contact closure or 0-24V DC\u003c\/td\u003e\n                \u003c\/tr\u003e\n                \u003ctr\u003e\n                    \u003ctd\u003e\u003cstrong\u003eCommunication Protocol\u003c\/strong\u003e\u003c\/td\u003e\n                    \u003ctd\u003eCresnet® (4-wire: 24V, Y, Z, G)\u003c\/td\u003e\n                \u003c\/tr\u003e\n                \u003ctr\u003e\n                    \u003ctd\u003e\u003cstrong\u003eCresnet Power Draw\u003c\/strong\u003e\u003c\/td\u003e\n                    \u003ctd\u003e5.4 Watts (0.23 Amps @ 24V DC)\u003c\/td\u003e\n                \u003c\/tr\u003e\n                \u003ctr\u003e\n                    \u003ctd\u003e\u003cstrong\u003eMounting Space\u003c\/strong\u003e\u003c\/td\u003e\n                    \u003ctd\u003e9 DIN Modules (approx. 159 mm \/ 6.26 inches wide)\u003c\/td\u003e\n                \u003c\/tr\u003e\n                \u003ctr\u003e\n                    \u003ctd\u003e\u003cstrong\u003eOverride Feature\u003c\/strong\u003e\u003c\/td\u003e\n                    \u003ctd\u003eDedicated OVR terminals (dry contact) for system-wide force-on\/off\u003c\/td\u003e\n                \u003c\/tr\u003e\n                \u003ctr\u003e\n                    \u003ctd\u003e\u003cstrong\u003eEnvironmental\u003c\/strong\u003e\u003c\/td\u003e\n                    \u003ctd\u003eOperating Temp: 32° to 104°F (0° to 40°C); 10% to 90% RH\u003c\/td\u003e\n                \u003c\/tr\u003e\n            \u003c\/tbody\u003e\n        \u003c\/table\u003e\n    \u003c\/div\u003e\n\n    \u003ch2\u003eApplication Matrix\u003c\/h2\u003e\n    \u003cul\u003e\n        \u003cli\u003e\n\u003cstrong\u003eCommercial Office Lighting:\u003c\/strong\u003e Acts as the primary switching workhorse in electrical closets, mapping the 8 digital inputs to local room occupancy sensors to reduce latency and free up Cresnet bandwidth.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eHigh-End Residential:\u003c\/strong\u003e Provides centralized, noiseless switching for non-dimmable landscape lighting, water features, and exhaust fans, integrated directly into a Crestron Home or custom SIMPL Windows program.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eMission-Critical Environments:\u003c\/strong\u003e The isolated inputs provide a hardwired fail-safe.

Unlike the standard DIN-8SW8, this model has a dedicated terminal block for 8 local digital inputs. This allows you to wire standard light switches, motion sensors, or contact closures directly to the module.

When this terminal is shorted to ground (via an external contact closure, such as a fire alarm relay or master override switch), the module enters Override Mode. The OVR LED turns red, Cresnet commands are ignored, and all relays immediately snap to their pre-programmed override state (typically all ON or all OFF) to ensure life safety or security lighting.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eCan I control 277V commercial lighting circuits with this module?\u003c\/strong\u003e Yes.
