COVID-19 Update (May 21st) — While our offices remain closed to the general public, Musson has resumed selected operations in compliance with county guidelines. Non-contact pickup is available for customers who place their order online or by email with our sales/rentals team.
While most of our team continues to work remotely, select employees have their direct extension forward to their cell phone. If unavailable, you can leave a voicemail. In an emergency, please contact us at COVIDfirstname.lastname@example.org or by leaving a voicemail in our general mailbox, which is closely monitored.
The Relay Module is a dual, plug-in mechanical relay assembly for use in all Unison/Sensor3 Series Racks. Each Relay Module provides two electrically held relays, in the same form factor as standard dimmer modules. This enables designers to mix and match dimmer and relays for control of diverse loads. Ideal for control of non-dimmable load types such as HID lamps. Standard Relay Modules provide cost-effective switching while Advanced Features Relay Modules enable dimmer-specific feedback of load circuit data while performing switching in AF-capable Sensor+ dimmer enclosures.
Dual 15A or 20A Relays
Optional Advanced Features (AF) version for compatible Sensor Racks.
Works great with most:
Non-dimmed On/Off loads
LEDs¹, Moving lights, fog machines, and other powered effects
Power for fans and standard outlets
High Intensity Discharge ballasts (Metal Halide and High Pressure Sodium)
Withstand hot-patching of cold loads up to full rating
100,000A Short Circuit Current Rating
UL and cUL Listed for continuous duty at 100% of rated load
All available spaces in a rack must be filled to ensure proper cooling. Use Air Flow modules to complete a rack when fewer than the maximum number of circuits are required. For example, a 6-module rack powering 8x 20A dimmers requires 4x D20 modules and 2x Air Flow modules.
¹ Only for LEDs controlled via DMX. Theatrical line-dimmable LEDs can typically use a standard D20 module (not guaranteed). For architectural LEDs or best performance look at the Electronic Reverse Phase Module (ELV10).
