Description

HDL M/R4.16.1-CD KNX four-channel high-power switch actuator with current detection. It uses magnetic-latching relays for compatible lighting and electrical switching circuits in an ETS-programmed KNX installation.

Control and monitoring

  • 4 independently controlled 16 A outputs (rated load category applies)
  • Current reporting, current surveillance, threshold comparison and conformance detection
  • KNX scenes, switching delays, status feedback, staircase timing and configurable logic
  • Logic functions AND, OR and XOR; PWM output for suitable heating applications

Technical specifications

  • KNX bus: 21–30 V DC, approx. 15 mA at 30 V
  • Switched mains: 120/240 V AC, 50/60 Hz
  • Physical dimensions: 90 × 72 × 64 mm
  • Net weight: 257 g
  • 35 mm DIN-rail installation; flame-retardant nylon enclosure, IP20
  • Ambient operating range: −5 to +45 °C

Installation

Relay protection, wiring, actual lamp or motor load class and inrush current must be evaluated for each channel by a qualified electrician. ETS programming is required; do not assume compatibility with non-KNX networks.
