The Rhombus AC-CON-DC20 is a cloud-managed 4-door access control panel designed for enterprise-grade physical security systems. It functions as the central controller that connects door readers, locks, sensors, and request-to-exit (REX) devices into a single managed platform. The unit supports up to four controlled doors and is designed to work with Rhombus access hardware such as DR20 and DR40 readers as well as compatible third-party Wiegand or OSDP devices over RS-485. It provides relay outputs for controlling electric strikes or magnetic locks, along with supervised inputs for door position sensors and REX devices. The controller is built for centralized deployment in commercial environments, allowing administrators to manage access permissions, door schedules, and event logs through the Rhombus cloud platform. This enables remote configuration and real-time monitoring of entry activity across multiple locations. SKU: AC-CON-DC20 Categories: Access Control, Access Control Hardware Brand: Rhombus
