Device translates and conditions the 24V digital output of sensors and switches
Maxim MAX31915 octal digital input translator is now in stock at Mouser.
The device translates and conditions the 24V digital output of sensors and
switches used in industrial, process, and building automation. These output
signals are converted into 5V CMOS compatible signals required by
The device provides the front-end interface circuit of a programmable logic
controller (PLC) digital input module. The signal voltage translation is
performed in conjunction with input current limiting and low-pass filtering.
Input current-limiting allows a significant reduction in power consumed from
the field-supply voltage, as compared to traditional discrete
resistor-divider implementations. Selectable on-chip low-pass filters allow
flexible de-bouncing and filtering of sensor inputs based on the
application. When no filtering is selected, the IC is capable of detecting
pulses as short as 0.75µs at its field inputs.
Applications include digital input modules for programmable logic
controllers (PLCs), industrial automation, building automation and process
