Technical data
• Two outputs for switching and dimming resistive, inductive
or capacitive loads
• Automatic adjustment of leading-edge or trailing-edge
control, depending on the connected load type
• Rated operational voltage AC  V
• Rated frequency  –  Hz
•  VA per output or  VA if only one output used
• No required minimum load per output
• Electronic protection for each output against overload,
short-circuit and overheating
• Screw terminals for connecting untreated single-core,
stranded or multi-core conductors, . to . mm²
• Bicolor LED for indicating switching status (red = ON, green
= OFF) or errors (blinking orange), for each output
• Electronics operated via bus voltage
• Designed for DIN rail mounting on a TH mounting rail
according to DIN EN 
• Maximum width  module units ( MU =  mm)
• Operating mode separately selectable for each output
(normal mode, one- or two-level timer mode, blinking)
• Additional object for each output for blocking/releasing the
output
• Sending of status objects on request and/or automatically
after a change
• Adjustable blocking time for sending status objects after
restart and bus voltage recovery
• Adjustable dimming value for each output in case of bus
voltage failure and recovery
• Additional night mode object for time-limited switching
on the output (and hence illumination) at night
• Adjustable ON period at night or with timer mode
• Selectable warning of imminent switching off the illumi-
nation by dimming to % of the previous dimming value
during night mode or timer mode
• Integrated -bit scene control and integration of each output
in up to  scenes
• Selectable counting of operating hours and with threshold
monitoring of the operating hours
• Selectable counting of load cycles and with threshold
monitoring of the load cycles
• Building site function for switching light without commis-
sioning with ETS of the dimmer with Engineering Tool
