MAX31915

Industrial, Octal, Digital Input Translator

General Description

Beneﬁts and Features

● Flexible Supply Options Enables Usage in 24V, 12V,

The MAX31915 translates and conditions the 24V

digital output of sensors and switches used in industrial,

process, and building automation to 5V CMOS-compatible

signals required by microcontrollers. It provides the front-

end interface circuit of a programmable logic controller

(PLC) digital input module.

and 5V Supplied Systems

• 7V to 36V Wide Operating Field Supply Range

• Device Can Be Optionally Powered from the Logic-

Side Using a 5V Supply

● Low Power and Low Heat Dissipation

• Very Low Quiescent Current

The signal voltage translation is performed in conjunc-

tion with input current limiting and lowpass filtering. Input

current-limiting allows a significant reduction in power

consumed from the field-supply voltage, as compared to

traditional discrete resistor-divider implementations.

• Extremely Accurate and Stable Input Current Limiters

● Configurability Enables a Wide Range of Standard

and Custom Applications

• Conﬁgurable Inputs for IEC 61131-2 Input Types 1,

2, and 3 or for Standard CMOS Logic Levels

• 0.5mA to 6mA Conﬁgurable Input Current Limiting

• Selectable Input Filtering and Debounce: 0, 25µs,

0.75ms, and 3ms Settings

Selectable on-chip lowpass filters allow flexible debouncing

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.

● High Integration Reduces BOM Count and Board Space

• 8 High-Voltage Input Channels (36V Max)

• 8 CMOS Logic Outputs for High-Speed Simultaneous

Transfer of All Input States to the Controller

• On-Chip 5V Regulator

All 8 input channels are translated to CMOS logic levels and

are presented in parallel on the eight output pins for direct

or galvanically-isolated interface with a controller ASIC or

micro.

The on-chip 5V voltage regulator can be used to power

external optocouplers, digital isolators, or other external

5V circuitry.

• On-Chip Overtemperature Indicator

• On-Chip Field-Supply Voltage Monitor

• High HBM ESD Immunity on all Field Input Pins

(15kV HBM)

For ultra-low-power applications and lowest possible heat

dissipation, Maxim Integrated plans to offer a pin-compati-

ble version of this device; the MAX31914. The MAX31914

uses patent-pending circuit techniques to achieve further

reduction of power beyond what is possible by input

current limiting alone. Contact the factory for availability.

Applications

● Digital Input Modules for Programmable

Logic Controllers (PLCs)

● Industrial Automation, Building Automation

● Process Automation
