Alpha RY008AE 8-Output Signal Relay Board

Optimize PC-based intercom, access control and security workflows with the Alpha Communications RY008AE 8-Output Signal Relay Board. Designed for AlphaEntry systems, this relay board delivers eight timed SPDT relay outputs triggered over RS232 for reliable control of doors, gates, lighting, alarms and third‑party security devices. The RY008AE is powered by a safe 5VDC, 2A plug‑in supply and mounts directly to finished walls or wooden mounting boards to minimize enclosure needs and installation time.

Technicians and integrators benefit from positive screw terminal connections, jumper-configurable NO/NC contacts, and diagnostic LEDs on each channel for fast commissioning and troubleshooting. Because multiple RY008AE units (or mixed RY032AE units) can be used on a single AlphaEntry system, the board scales with facility needs—from small multi-tenant entries to larger surveillance and monitoring deployments. Built for dependable, low-voltage operation in security and intercom environments, the RY008AE simplifies integration with existing RS232-based control architectures. Add the RY008AE to your next intercom or access control project to improve reliability, reduce install time, and expand control capability.

• Scalable control for access and security: expand or mix multiple RY008AE and RY032AE boards to add timed relay outputs as your system grows.
• Simple, fast installation: surface-mount design and positive screw terminals reduce labor time and simplify field wiring on finished walls or mounting boards.
• Reliable, low-voltage operation: Class II 5VDC/2A power keeps installations safe while supporting consistent relay performance.
• Clear diagnostics: individual LEDs on each of the 8 relays provide instant visual confirmation for troubleshooting and monitoring.
• Flexible relay behavior: each SPDT relay ships NO and can be quickly jumper-configured to NC to match diverse door, gate, or alarm requirements.
