You need to unlock a door, trigger an alarm panel, or switch a machine from across the network — and you need it logged. The CyberData SIP Dual Relay Controller handles two high-amperage relays over your IP network. PoE-powered. Control via web interface or DTMF. Airlock mode for sequential access. Internal 12V @ 500mA supply for strikes, or run external power. Every event gets a battery-backed timestamp you can download. Pair with the CyberData Remote Call Button (011508, sold separately) for physical button activation on top of network control
