Product Overview

The PCLT-2AT4-TR is a dual current limited overvoltage protected Digital Termination Device designed for 24VDC automation applications. It is compatible with the type 2 (7.5mA) or type 3 (3mA) characteristic of the IEC 61131-2 standard. An internal resistance RREF allows the limiting current value to be adjusted from 3 to 7.5mA. 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 output block of each termination channel transfers the input logic state to a logic output and a light emitting diode (LED).
  • 2-channel Topology, low side input with common ground
  • LED drive for sensor status - 4.4mA typical with RREF = 10kR
  • Input protection (RI= 750R, CIN = 22nF)
  • IEC 61000-4-2 ESD, level 4 - in contact ±8kV; in air ±15kV
  • IEC 61000-4-5 voltage surge, Level 3 - ±500V with 42R series resistor in differential mode
  • IEC 61000-4-4 transient burst immunity - ±4kV peak voltage, 5kHz repetitive rate
  • IEC 61000-4-6 conducted RFI - 10VRMS
  • Input protection against -30V reverse polarity
  • Enable input to meet type1, 2 and 3 characteristics of IEC 61131-2 standard
  • Compatible operation with 2 and 3 wires proximity sensor according EN60947-5-2 standard
  • Reduced overall dissipation
  • Enhanced functional reliability
  • Compact with high integration
  • Surface mount package for highly automated assembly
  • Insensitive to the on-state sensor impedance
  • -25 to 150°C Junction temperature range
