Lighting Controller – Eight Channel
SL2108Description
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:
Two:
- 0 – 5VAC
- 4 – 20mA DC
Communications:
RS-485, half-duplex, TCSbus
Supply Voltage:
24VAC +/– 20%
Features
- 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
