ISO1211 Description

Short technical summary and product information.

The ISO1211 from Texas Instruments is a single-channel isolated digital input receiver compliant with IEC 61131-2, Type 1, 2, and 3 characteristics. It is designed for 24V to 60V digital input modules, supporting input voltages from 9V to 300V DC and AC with external resistors. This device offers accurate current limiting for low-power dissipation, with a typical range of 2.2mA to 2.47mA for Type 3 and adjustable up to 6.5mA.

The ISO1211 operates with a wide supply voltage range of 2.25V to 5.5V and supports high data rates up to 4Mbps. It features a high input-voltage range with reverse polarity protection up to ±60V and high transient immunity of ±70kV/µs CMTI. The device is configurable as a sourcing or sinking input and eliminates the need for a field-side power supply.

Packaged in a compact SOIC-8 surface-mount package, the ISO1211 operates within an ambient temperature range of -40°C to +125°C. It is suitable for applications such as Programmable Logic Controllers (PLCs), digital input modules, mixed I/O modules, motor drive I/O, and data acquisition systems. The device also offers functional safety capabilities and meets various safety-related certifications including UL 1577 recognition.
