المميزات والفوائد
- 10 to 26 I/O in a single DIN rail unit replaces complex relay-timer wiring diagrams for simple automation tasks, reducing panel wiring labour time by 50–70% compared to equivalent discrete relay logic.
- Front panel keypad and LCD display allow programme creation and monitoring without a PC, enabling panel builders and site technicians to create and modify control logic without a laptop on-site.
- Modbus RTU communication in SR3 models connects Zelio to Harmony HMI panels, supervisory PLCs, and SCADA systems, enabling small smart relay nodes to report status and receive setpoints over a shared Modbus network.
- Built-in real-time clock with weekly and seasonal programmable schedules enables time-based control of lighting, ventilation, and irrigation systems without external timer modules.
- Four analog inputs in SR3 models accept 0–10 V and 0–20 mA signals from temperature, pressure, level, and flow sensors, enabling closed-loop process control for simple applications without a separate PLC.
- Zelio Soft simulation function tests programme logic on the PC before download, catching logical errors before panel commissioning and reducing site debugging time for new programme development.
- Parameter storage and programme upload/download via front panel or PC USB preserves programme backup and enables rapid programme restore after device replacement, minimising downtime for small automation control panel maintenance.
التطبيقات الصناعية
- Duplex pump alternation control panels in building services plant rooms across Saudi commercial buildings, where Zelio SR2 provides lead/lag alternation, run-time equalisation, and high-level alarm without a full PLC.
- Water tank level control panels for overhead and underground tanks in residential compounds and commercial buildings, where Zelio SR3 with analog level input manages fill and pump stop sequences automatically.
- Ventilation system sequencing in industrial facilities and warehouses, where Zelio controls fan start/stop sequences, temperature setpoint control, and CO sensor interlocking without full PLC infrastructure.
- Air compressor control panels for small packaged compressors in workshops and light industrial facilities, where Zelio manages pressure setpoint control, auto-restart, and hour meter reporting.
- Agricultural irrigation zone control in Saudi landscaping and farming projects, where Zelio SR3 with soil moisture analog inputs manages irrigation zone timing and real-time feedback control.
- Water treatment dosing system control for small chlorination and pH adjustment applications at NWC rural water supply installations, where Zelio SR3's analog inputs receive residual chlorine and pH sensor signals.
- Small packaged equipment OEM control including water softeners, UV sterilisers, and filtration systems where Zelio provides cycle sequencing, fault alarm output, and Modbus status reporting to building management systems.
