ISO1212 Description
The ISO1211 and ISO1212 devices are isolated 24-V to 60-V digital input receivers, pliant 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...
