LynTec’s retrofit and value relay products are engineered to solve common power control challenges in existing facilities. Our retrofit controllers like the RBLC and MRTS series add DMX, serial, or sequencing capabilities to standard Square D panels, enabling modern control over legacy infrastructure. This approach saves significant cost and complexity compared to a full panel replacement.
For distributed applications, simple and robust relay boxes like the DDR provide portable, IP-rated DMX control exactly where it’s needed. This is ideal for controlling remote fixtures, projectors, or temporary equipment while minimizing complex and expensive cable runs back to a central rack.
Targeted control for existing systems.
Upgrade existing panels, not replace them.
Extend power control to remote and portable equipment.
Engineered for simple, reliable integration.
Your questions, answered.
Yes. The DDR Dual DMX Relay is specifically engineered for these environments. It features a rugged, IP-rated housing that protects the internal components from dust and moisture, making it a reliable choice for outdoor architectural lighting, temporary events, and touring productions. Its compact, portable design and flexible mounting options allow for rapid and secure deployment on truss or scenery.
Yes, our modular design is engineered for forward compatibility. Most modern LynTec panels, including the RPC, RPCR, and NPAC series, are designed to accept field-installable modules. This allows you to add new capabilities like DMX, sACN, or BACnet control to an existing installation.
For very old or legacy systems, we recommend consulting our engineering team to verify compatibility and explore available upgrade paths. The goal is to extend the life of your core infrastructure whenever possible.
Absolutely. This is a primary application for our retrofit controllers. By installing a kit like the MRTS series into a compatible Square D panel, you can add intelligent startup and shutdown sequencing to existing circuits. This protects sensitive audio and video equipment from damaging inrush currents without needing to install a new, dedicated sequencing panel.
Yes, the SC Series is designed for both new construction and retrofits. You can specify a complete new panelboard or load center for a new build. For existing infrastructure, you can select a relay-only panel to add serial control capabilities to a system that is already in place.
LynTec retrofit controllers are designed to operate motorized circuit breakers. They provide the mechanical interface and control logic to physically switch these specific types of breakers on and off via DMX, serial, or a sequencing command. Standard thermal-magnetic breakers cannot be remotely controlled and would need to be replaced with their motorized equivalents during the retrofit installation.
Our value relay and retrofit solutions are designed for seamless integration into existing AV and lighting systems. They primarily use industry-standard protocols like DMX and RDM for lighting control, as seen in our DDR relay. For broader system integration, many of our retrofit controllers also support RS-232 serial commands. This ensures compatibility with a wide range of third-party control systems.
Placing control relays near the fixtures, a key feature of our lighting ecosystem, significantly simplifies infrastructure. This distributed approach reduces the length and complexity of power cabling, which minimizes voltage drop and saves on material and labor costs. It’s an efficient way to manage power for fixtures spread across a large venue, truss, or architectural feature.
The SC Series is engineered specifically to integrate branch circuit control with legacy automation systems that use RS-232 serial communication. It provides a direct, native control path for older Crestron, AMX, or other serial-based controllers without requiring network gateways or protocol converters.
The RT Series is engineered for applications where direct, non-networked control is required for maximum reliability. Choose the RT Series when you need to integrate with systems like life safety alarms, simple key switches, or basic control panels that provide a relay output.
It is the ideal solution when network access is unavailable, unreliable, or when advanced monitoring and remote management are not required for the equipment being controlled.
A relay box like the DDR Dual DMX Relay is ideal for controlling distributed or remote equipment where running dedicated circuits back to a central panel is impractical or too costly. Use a relay box for portable AV gear, fixtures on a lighting truss, or temporary outdoor installations. It places simple, reliable DMX-controlled power exactly where you need it, simplifying cabling and setup.
Our upgrade kits are engineered to retrofit many existing LynTec panels and select third-party enclosures. The primary goal is to replace the legacy controller while preserving the investment in the main enclosure, conduit, and wiring.
Because every installation has unique factors, we recommend contacting our engineering team with the make and model of your existing panel. They can confirm compatibility and help you identify the correct kit for a successful modernization project.
Our retrofit controllers, such as the RBLC and MRTS series, are specifically engineered to integrate with common Square D load centers and panelboards. This design allows you to add modern, motorized breaker control to legacy infrastructure without requiring a complete and costly panel replacement.
For specific compatibility questions, it is always best to consult the product documentation or contact our engineering team to ensure a proper fit for your project.
