Product overview

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.
  • All features

    • Operating ambient temperature: - 25 to 85° C
    • 4 channel topology
    • Current limiter:IGEN = 3 mAInput current limiter activation voltage < 5 VTemperature compensated operation
    • Wide range input dc Voltage:VI= - 0.3 to 30 V with RI = 0VI = - 30 to 30 V with RI = 1.8 kΩLow side configuration with common ground
    • Input protection (RI = 1.2 kΩ):IEC 61000-4-2 electrostatic discharge ESD, Class 3In contact, ± 6 kV; in air, ± 8 kVLevel B: temporary disruption; no change of opto-coupler stateIEC 61000-4-5 voltage surge, Class 3± 1000 V with 42 Ω serial resistor in differential modeLevel B: temporary disruptionIEC 61000-4-4 transient burst immunity± 4 kV peak voltage; 5 kHz repetitive rateLevel A: fully functional
    • Opto-coupler drive:No coupler activation below 1.5 mA input current
