  • CLT01-38S4 adds to the existing current limiter family. Still focusing on power consumption savings, the whole series allows each customer to find the right solution.

    The CLT01-38S4 is an octal input termination device with a high speed SPI output. Its maximum input data rate is 400 kbps while the output SPI speed is 6.25 MHz.
    As in previous versions, robustness is a key feature of CLT01-38S4. The product is compliant with surge standards defined in IEC 61000-4-x.
    It can run all types of sensor according to IEC 61131-2. Type 1 and 3 with a 2.35 mA limited current and type 2 using two inputs per sensor with the correct RREF.

    Key Features

    • 8-input circuit in common ground low side topology
    • Wide range input DC voltage VI: -30 V to 35 V
    • On state threshold: < 11 V with RI= 2.2 kΩ
    • Off state threshold: Iin> 1.5 mA or Vi> 5 V
    • Protected against -30 V reverse polarity
    • Typical ILIM= 2.1 to 2.6 mA adjustable current limiters
    • Tight current tolerance including temperature compensation: ±10%
    • Serial output with an SPI communication bus
    • Clock frequency up to 6.25 MHz
    • CPHA = CPOL = 0 bus master operation
    • Multi CLT operation in daisy chain connection
    • 16-bit mode: 8 bits for data / 8 bits for control
      • Minimum capture time: 4 μs
      • Input data rate: 200 kbps/100 kHz
      • Minimum propagation transfer time: 7 μs
    • 8-bit mode: 8 bits for data
      • Minimum capture time: 2.5 μs
      • Input data rate: 400 kbps/200 kHz
      • Minimum propagation transfer time: 4 μs
    • VCC = -0.3 to +35 V with RC = 2.2 kΩ
    • Ambient temperature range: -25 to +85°C
    • Digital inputs for programmable logic controller and decentralized I/O modules
    • Benefits
      • Enables input to meet type 1, 2 and 3 characteristics of IEC 61131-2 standard
      • Compatible operation with 2 wires proximity sensor according EN 60947-5-2 standard
      • Compact board with surface mount integration and reduced count of isolated couplers
      • Reduces the count of input-output of the bus controller circuit
      • Provides energy-less input LED visual status
      • Enhanced functional reliability
      • Built-in over voltage robustness and immune data transfer
      • Reduced dissipation: 78 mW max. per channel
    • Complies with following standards (RI= 2.2 Ω, RC= 2.2 Ω, C = 33 nF):
      • Electrostatic discharge, IEC 61000-4-2:
        • ±8 kV contact discharge
        • ±15 kV air discharge
      • Electrical transient immunity IEC 61000-4-41:
        • FSCK= 6.25 MHz, ±3 kV
        • FSCK= 10 kHz, ±4 kV
      • Voltage surge IEC 61000-4-5
        • Input: ±15 kV
        • Power supply: ±2.5 kV
