Description

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...
