Description
FMR15108 can be used in noisy environment and is least affected by electrical interference. This makes FMR15108 an ideal choice for use in heavy industrial environment.
Case
The FMR1510812R, FMR1510824R can be supplied without a case, this allows the receiver to be integrated according to your needs.
The C160 case (weather proof) can be used to enclose the FMR1510812R, FMR1510824R receiver. The receiver with a case is known as FMR1510812RE, FMR1510824RE.
Different Modes for each Output
Modes are user selectable from the 4-way dip switch, shown below.
Coding
The 12 way dip switch on the receiver sets the 12 bit unique code for the system. This has to be matched to that on the transmitter.
