3 Aspect Signal Slave Module
The SD-004 slave module is used with an SD-001 central control module to control signals fitted with three LED lights.
It has one output for controlling one three aspect signal eg red/yellow/green.
The module powers the signal lights directly and a series resistor is not required.
One SD-001 and four SD-004 modules can drive four three light signals.
