Five Channel Lighting Control Module


The SL2105 is a microprocessor based lighting control module designed to control up to five lighting channels.


• Stand-alone or network operation

• 365-day programming for each circuit

• Analog inputs for photo sensors with the ability to remotely adjust sensitivity level

• Analog input for energy consumption with the ability to limit loads.

• Digital photocell inputs

• Astronomical clock

• Remote or local override of each circuit

• External time clock or occupancy sensor input for each circuit

• LEDs for monitoring status

• No battery required for control parameters, schedules or clock

• Vanishing holidays

• End of occupancy blink warning

• Selectable normally open or normally closed relay outputs
