Lighting Controller – Eight Channel



The SL2108 is a microprocessor-based lighting controller that will manage up to eight lighting channels (digital inputs). The controller has two additional analog inputs and 10 digital outputs.


Digital Inputs:

Eight momentary override

Digital Outputs:

10 (SPST dry contact, 24VAC @2A) configurable

Analog Inputs:


  • 0 – 5VAC
  • 4 – 20mA DC


RS-485, half-duplex, TCSbus

Supply Voltage:

24VAC +/– 20%


  • 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
