The SL MA-110 serves as the interface between the fiber optic sensor and the processing unit. It should be installed indoors or inside a weatherproof road side cabinet.  The sensor system consists of the SL MA-110 interface with transmitter (LED) and receiver (photodetector) connected by fiber optic feeder cable to the fiber optic load sensor. The interface responds to the optical sensor signal in a dynamic (AC-coupled) manner, i.e. the electrical signal caused when a load is applied to the sensor decreases to zero as the load remains applied. At a preset threshold, a digital trigger signal is generated. This signal is automatically reset after a certain time period. These characteristics allow the SL MA-110 interface to operate without the need for adjustment. If the interface detects an interruption in the light transmission path, it generates a digital error signal. Both digital signals are transmitted via optocouplers which behave similar to relays, allowing the use of a variety of output circuitry. The dynamic analog load signal and the light power monitor signal also have their own output clips.
