Bus Extender
PB4UIN
FLEXBOOL PB4UIN is a Power Bus Extender with 4 universal inputs. It communicates with the PLC by means of a 2-Wire bus (Power + Data) with a total length up to 500 meters. Up to 32 extenders can be connected in a daisy chain.
Each of the four inputs can be used as an analog input (0-10V, resolution 0.01V), current input (0-20mA, resolution 0.01mA), temperature input for RTD sensors (PT1000), temperature input for NTC sensors (thermistors 1-10kOhm), or digital input (for level and pressure switches, relay contacts, buttons, and selector switches). The extender is compatible with all FLEXBOOL PLC models that support Power Bus communication (PB models).
