Hytronik HC419VRC/R High-Bay HF Motion Sensor with Tri-Level Control

The Hytronik HC419VRC/R is a high-frequency (5.8GHz microwave) occupancy detector designed for indoor high-bay applications like warehouses and storage rooms. It provides automated tri-level dimming control via a 1-10V interface, featuring a zero-crossing detection circuit to minimize in-rush current and extend relay life.

Technical Specifications

• Operating Voltage: 120-277VAC, 50/60Hz.
• Load Rating (Capacitive): 400W @ 120VAC; 1000W @ 277VAC.
• Detection Range: Max 16m x 15m (D x H) with a 30° to 150° angle.
• Standby Power: < 0.5W.
• Operating Temp: -20°C to +60°C.
• IP Rating: IP20.

Key Functionality

• Tri-Level Control (Corridor Function): Manages three light levels (100%, dimmed, and off) based on two selectable waiting periods: hold-time and standby period.
• Synchronisation: Up to 10 units can be connected in parallel via "SYNC" terminals; if one sensor triggers, the entire group activates.
• Daylight Monitoring: Features a 24-hour "smart photocell" function that can maintain dimming levels at night and switch off completely when natural light exceeds the threshold.
• Manual Override & Semi-Auto Mode: Supports push-switch input for manual on/off, brightness adjustment (10%–100%), or absence detection mode.

Configuration & Controls

• Settings can be adjusted via onboard DIP switches or the HRC-05 remote control.
• Hold-time: 5s to 30min14.
• Standby Period: 0s, 10s to 1h, or +∞ (permanent dimming).
• Standby Dimming: 10%, 20%, or 30%
• Daylight Threshold: 2–50 lux or disabled
