工业, 八, 数字输入转换器, 7 V至36 V电源, TSSOP-38

The is a industrial, octal, digital input translator in 38 pin TSSOP package. It translates and conditions 24V digital output of sensors and switches used in industrial process and building automation to 5V CMOS-compatible signals required by microcontrollers. It provides 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 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. It is used in digital input modules for programmable logic controllers PLCs, industrial automation, building automation and process automation.
