ISO1211DR Single-channel Isolated 24V~60V Digital Input Receiver for Digital Input Modules - SOIC-8

Datasheet

The ISO1211DR device are isolated 24-V to 60-V digital input receiver, 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, th ISO121 device provide a simple, low-power solution with an accurate current limit to enable the design of compact and high-density I/O modules. These devices do not require field-side power supply and are configurable as sourcing or sinking inputs.

The ISO1211DR device operate over the supply range of 2.25 V to 5.5 V, supporting 2.5-V, 3.3-V, and 5-V controllers. A ±60-V input tolerance with reverse polarity protection helps ensure the input pins are protected in case of faults with negligible reverse current. These devices support up to 4-Mbps data rates passing a minimum pulse width of 150 ns for high-speed operation. The ISO1211 device is ideal for designs that require channel-to-channel isolation and the ISO1212 device is ideal for multichannel space-constrained designs.
