SmartLink SML4410 I/O Control & Alarm Box
A standalone control and alarm box that reads 4 dry-contact inputs and drives 4 dry-contact outputs over RS-232 or Ethernet, triggering SmartLink software alarms, notifications, and automated responses in real time.
How SmartLink Connects Your Devices
Four dry-contact inputs feed SmartLink software, which evaluates alarm conditions and drives four dry-contact outputs — while logging CCTV footage and device location for full visibility.
SmartLink Software
Evaluates alarm conditions, logs events, and routes signals between inputs and outputs in real time.
A Compact, Standalone Unit
Model SML4410-V1 packs serial and Ethernet connectivity, 4 inputs, 4 relay-rated outputs, and an analog temperature channel into a compact panel-mount enclosure.
Alarm Logic Without Writing Code
SmartLink software turns raw dry-contact signals into configurable alarms, automated outputs, and reports — no PLC programming required.
Dual Connectivity
Communicate over RS-232 serial or Ethernet RJ45, so SmartLink drops into legacy panels and modern IP networks alike.
4-In / 4-Out Dry Contact I/O
Four dry-contact inputs and four 5A-rated dry-contact outputs give you room to sense and switch real equipment.
Configurable Alarm Conditions
Define trigger conditions per input and fire custom Email or LINE notifications for each one.
Runtime Hour Tracking
Accumulate operating hours per input to schedule preventive maintenance before equipment fails.
Duration-Based Alerts
Flag conditions that persist too long — like a door or cabinet left open beyond its allowed time.
Power Failure Detection
Wire a power-sense input to get an immediate alert the moment mains power is lost.
Remote Output Control
Trigger doors, lights, sirens, or electronic locks directly from the SmartLink software.
Temperature Threshold Control
Read an analog temperature sensor and drive an output between two setpoints, with fan-rotation monitoring support.
CCTV & Map-Based Location
View CCTV footage over RTSP and visualize every device's live status and GPS location on a map, plus daily reports and a mobile app for real-time monitoring.
