Cardin 2CH Receiver

Description

The Cardin RQM504C2 is a compact 2 channel gate receiver designed to provide secure and reliable radio control for automated gates, doors and access systems. Acting as the central connection point, it enables communication between transmitters, keypads and automation equipment. Operating on Cardin’s S504 radio platform, the RQM504C2 uses 433MHz rolling code technology with 128-bit encryption. As a result, it ensures secure signal transmission and protection against unauthorised access across all connected devices. The receiver supports the memorisation of up to 1000 user codes, allowing it to manage multiple remotes, wireless keypads and access control devices within a single system. With 2 independent channels, the RQM504C2 can control two separate automation functions, such as gate opening, pedestrian access or auxiliary devices like lighting or alarms. Designed for flexible installation, the unit features an electronic circuit with a 10-way terminal block and is supplied with two impulsive relays, enabling straightforward integration into a wide range of automation systems. Housed in a compact indoor enclosure with IP20 protection, the RQM504C2 is ideal for installation within control panels or protected environments. It also supports extended signal performance when paired with the ANS400 external antenna, achieving ranges of up to 100–150 metres depending on installation conditions. Designed as a core system component, the RQM504C2 integrates seamlessly with Cardin transmitters, wireless keypads and access control devices, enabling secure and scalable automation control. Finally, backed by Downee, the RQM504C2 combines premium European engineering with local availability, technical support and full compatibility across the Cardin automation range.
