Manufacturer: Texas Instruments

Overview: Product Folder Order Now Technical Documents Tools & Software Support & Community Reference Design ISO1211, ISO1212 SLLSEY7F – JUNE 2017 – REVISED APRIL 2020 ISO121x Isolated 24-V to 60-V Digital Input Receivers for.

General Description

The ISO1211 and ISO1212 devices are isolated 24-V to 60-V digital input receivers, compliant to IEC 61131-2 Type 1, 2, and 3 characteristics.

These devices enable 9-V to 300-V DC and AC digital input modules in programmable logic controllers (PLCs), motor-control, grid infrastructure, and other industrial applications.

Unlike traditional optocoupler solutions with discrete, imprecise current limiting circuitry, the ISO121x devices provide a simple, low-power solution with an accurate current limit to enable the design of compact and high-density I/O modul

Key Features

  • 1 Compliant to IEC 61131-2; Type 1, 2, 3 characteristics for 24-V isolated digital inputs.
  • Supports 9-V to 300-V DC and AC digital input designs using external resistors.
  • Accurate Current Limit for Low-Power Dissipation:.
  • 2.2 mA to 2.47 mA for Type 3.
  • Adjustable up to 6.5 mA.
  • Eliminates the need for field-side power supply.
  • High input-voltage range with reverse polarity protection: ±60 V.
  • Wire-break detection (refer to TIDA-.
