FBs-B2A1D is one of the analog I/O boards of FATEK FBs series PLC. For analog output it provides 1 channel of 12-bit (coded in 14 bits) output signal. For safety, the output signal will be automatically forced to zero(0V or 0mA) when the module is not serviced by CPU for 0.5 second. For analog input it provides 2 channels of A/D inputs with 12-bit (coded in 14 bits) resolution. The Input/Output signal types (voltage or current) can be selected by the field wiring.
