The PCLT-2A is a dual input current limiter device designed for 24 V DC automation applications.
This product is compatible with the type 2 (7.5 mA) or type 3 (3 mA) characteristic of the IEC 61131-2 standard. An internal resistance RREFallows the limiting current value to be adjusted from 3 to 7.5 mA.
Each input voltage clamping block protects the module input against electromagnetic interference such as those described in the IEC 61131-2 standard, IEC 61000-4-2 (ESD), 4-4 (transient burst), 4-5 (voltage surge) and 4-6 (conducted radio frequency interference) standards. The supply input is also designed with such a protection structure.
The low tolerance of the current limitation allows a drastic reduction in the dissipation of the input compared to a resistive input. The PCLT2 is packaged in TSSOP14 - a very low RTHexposed pad package that allows the PCB cooling pad to be reduced.
The output block of each termination channel transfers the input logic state to a logic output and a light emitting diode (LED).
