Description
ABB SA/S2.16.6.1 KNX 2-Fold Switch Actuator 16/20A C-Load with Current Detection, MDRC

The ABB SA/S2.16.6.1 is a high-performance 2-fold KNX switch actuator from ABB's i-bus® KNX range, designed for intelligent building automation. Featuring built-in load current detection per output channel, this DIN rail-mounted device enables precise monitoring and switching of capacitive (C-Load) and standard electrical loads — making it ideal for modern smart building installations.

Key Features
  • 2 independent output channels with floating contacts, each individually controlled via KNX
  • Built-in load current detection per output (detection range: 0.02–20 A, accuracy: ±2%)
  • Supports C-Load (capacitive load) including fluorescent lighting up to 16/20 AX at 250 V AC
  • No additional power supply required — operates directly on KNX bus voltage (21–31 V DC)
  • Manual actuation button with integrated contact position indicator on each channel
  • ETS-parameterized for flexible commissioning, including copy/exchange of output settings
  • DIN rail (MDRC) modular design, 2-module width (36 mm)

Applications
  • Office & Commercial Buildings — Centralized KNX control of lighting circuits, with real-time current monitoring to detect lamp failures or load faults automatically
  • Hotels & Hospitality — Guest room lighting and appliance control with occupancy-based switching and energy monitoring
  • Retail & Showrooms — Scheduled lighting control for display areas with load current feedback for maintenance alerts
  • Industrial Facilities — Switching of HVAC fans, pumps, or ventilation motors with current detection for equipment fault diagnostics
  • Smart Homes — Integration into KNX home automation for scene control, energy tracking, and remote switching of high-current loads
  • Educational & Public Buildings — Energy efficiency programs leveraging real-time load data to optimize consumption
Package Contents
  • 1 * ABB SA/S2.16.6.1 KNX 2-Fold Switch Actuator
  • Bus connection terminal (pre-installed)
  • Combo-head screw terminals for load connections
Why Choose ABB SA/S2.16.6.1?

Unlike basic relay modules, the SA/S2.16.6.1 integrates active current monitoring directly into the switching unit — eliminating the need for separate current transducers. This enables fault detection, energy logging, and load monitoring all within a compact 2-module DIN rail footprint, fully programmable through standard KNX ETS software.
