CLT3-4B

Current limited over-voltage protected quad digital termination

Features

■ 4 channel topology

■ Wide range input dc Voltage:

–VI= - 0.3 to 30 V with RI = 0

–VI = - 30 to 30 V with RI = 1.8 kΩ

– Low side configuration with common

ground

■ Current limiter:

–IGEN = 3 mA

– Input current limiter activation voltage < 5 V

– Temperature compensated operation

■ Opto-coupler drive:

– No coupler activation below 1.5 mA input

current

■ Input protection (RI = 1.2 kΩ):

– IEC 61000-4-2 electrostatic discharge

ESD, Class 3

In contact, ± 6 kV; in air, ± 8 kV

Level B: temporary disruption; no

change of opto-coupler state

– IEC 61000-4-5 voltage surge, Class 3

± 1000 V with 42

Ω serial resistor in

differential mode

Level B: temporary disruption

– IEC 61000-4-4 transient burst immunity

± 4 kV peak voltage; 5 kHz repetitive

rate

Level A: fully functional

■ Operating ambient temperature: - 25 to 85° C

Benefits

■ Reduced overall dissipation

■ Compact with high integration

■ Enables input to meet type 1 and 3

characteristic of IEC 61131-2 standard

■ Compatible operation with 2 and 3 wires

proximity sensor according EN60947-5-2

standard

■ Insensitive to the on state sensor impedance

■ Surface mount package for highly automated

assembly

■ Enhanced functional reliability

Applications

■ Industrial automation

■ Programmable logic controller

■ Communication field bus nodes

■ Peripheral input / output modules

■ Machine tool interface

Description

The CLT3-4 is a quadruple input digital

termination device designed for 24 V dc

automation applications. It provides the front-end

circuitry of a digital input module (I/O) in industrial

automation, and drives an isolating opto-coupler.

The pins ESD, COMIJ, COM (pins # 1, 3, 6, 8, 10, 11,

13, 15, 16, 18, 20) must be connected together

externally. This common pad COM is enlarged to

reduce the thermal resistance and improve the device

cooling. The COM and IN pins are designed to

minimize the EMI effects on the circuit.
