ISO1211 and ISO1212 devices are isolated 24V to 60V digital input receivers, conforming to IEC61131-2 Type 1, 2 and 3 features
These devices allow 9V digital input to 300V DC and AC modules in Programmable Logic Controllers (PLCs), Motor Control, Network Infrastructure, and Other Industry Applications
Unlike traditional optocoupler solutions with imprecise, discrete current limiting circuitry, ISO121x devices provide a simple, low-power solution , precise current-limit solution to enable compact, high-density I/O module design
These devices require no field-side power supply, and are configurable as sources or sinks of inputs
The devices ISO121x operate over the 2.25V to 5.5V supply range, compatible with 2.5V, 3.3V, and 5V controllers An input tolerance of ±60V with reversal
Polarity protection helps ensure input pins are protected in the event of a fault with negligible current reversal
These devices support up to 4 Mbps of data passing a minimum pulse width of 150 ns for high-speed operation
ISO1211 device is ideal for designs requiring channel-to-channel isolation and the ISO1212 device is ideal for multi-channel, space-constrained designs
