ISO1211D product

ISO1211D

Specialized

isolated digital inputPLC input24 V industrial I/OSOIC-8IEC 61131-2

ISO1211D is a single-channel isolated receiver for 24 V to 60 V PLC and industrial digital inputs. It combines adjustable input-current limiting with a 2.25 V to 5.5 V logic-side supply and 2500 VRMS isolation.

Best for

  • Single-channel isolated PLC digital inputs
  • 24 V industrial sensor and switch interfaces
  • Designs requiring low controlled input current

Avoid if

  • Applications requiring more than one input channel in one package
  • Field input conditions that can exceed ±60 V at IN or SENSE without external protection

Check before use

  • Select RSENSE for the intended input current limit
  • Select RTHR for threshold and surge-current requirements
  • Confirm thermal operation at maximum SENSE voltage
  • Maintain required PCB creepage and clearance
