The APPLETON SDUCFRELAYCARD is a relay card designed for use in heavy-duty electrical control applications. Relay cards of this type serve as interface components within control panels and automated switching systems, allowing low-voltage control signals to switch higher-load circuits. Licensed electricians and industrial controls technicians are the primary installers. The SDUCFRELAYCARD fits into modular control architectures where discrete relay outputs are required for system operation and sequencing.
This relay card is suited for commercial and industrial electrical installations where modular relay output expansion is needed within a control enclosure or panel assembly. It is intended for environments that demand reliable, repeatable switching performance in automated or semi-automated electrical control systems.
Designed as an OEM-style relay card replacement for compatible APPLETON heavy-duty control system assemblies. Refer to the system documentation or contact the manufacturer to confirm fitment for your specific control panel configuration.
Installation should be performed by a qualified electrician in accordance with applicable NEC requirements and local electrical codes. De-energize and lock out the control panel before handling or replacing any relay card. Verify that the relay card is fully seated in its designated slot before restoring power. Do not install in energized enclosures or expose the card to moisture during installation.
