Signature Module

SM

OPERATOR INTERFACE MODULE

The Miller Edge Signature Module converts a 10K or diode capacitor configured sensing edge or photo optic device output to a pulsed signal, as required by UL 325-compliant commercial door and automated gate operators. Both models are engineered to meet operator-specific input requirements and ensure reliable system compatibility. Built-in LED indicators provide clear status updates for power and fault conditions. Each module includes a standard junction box and is designed for quick, hassle-free installation.

Compatibility & Applications

For use with UL Listed operators that require a pulsed signal from connected safety devices.
