Technical Parameters Parameter Specification System / Standard KNX / EN 50090, ISO/IEC 14543 Bus Voltage 21 – 32 V DC (KNX SELV) Auxiliary Supply (Us) 24 V DC, SELV (±10%) Power Consumption • From KNX Bus: Typically < 10 mA • From Aux. Supply: Depends on relay state; ~20 mA per active relay + quiescent. Channels 2 Binary Inputs + 2 Relay Outputs (Typical interpretation of DACADAN) Binary Inputs • Type: Dry contact (potential-free) or voltage monitor (24V DC). • Function: Configurable as switch, push-button, counter, etc. via ETS software. Relay Outputs • Contact Type: 1 changeover (SPDT) per channel. (NO + NC + COM) • Rated Load (AC-1): 16 A / 250 V AC • Motor Load (AC-3): 10 A / 250 V AC (for squirrel-cage motors) • Inrush Current (Ic): 150 A (for a limited number of cycles). Electrical Life ≥ 100,000 operations at rated load (AC-1) Mechanical Life ≥ 1,000,000 operations Status Indication LED per channel (configurable) + LED for bus & power status. Local Manual Control Yes, via integrated pushbuttons (indicated by suffix E). Mounting 35 mm DIN Rail (EN 60715) Ambient Temperature Operating: -5°C to +45°C Storage: -25°C to +55°C Protection Degree IP20 (for mounting in a distribution board) Configuration Exclusively via ABB ETS (Engineering Tool Software) using a unique device database file.
