4 / 13 page Characteristics CLT3-4B 4/13 Figure 3. Typical junction to ambient thermal resistance versus copper surface under common pad (FR4 epoxy, copper thickness is 35 µm) 1.1 Functional 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. Available in a four channels configuration, it offers a high-density termination by minimizing the external components count. It is housed in a TSSOP20 surface mount package to reduce the printed board size. Made of an input voltage protection, a serial current limiting circuit and an opto-coupler driver, each channel circuit terminates the connection between the logic input and the associated high side sensor or switch. The CLT3-4 is a 3 mA quad channel device compatible the type 1 and 3 characteristics of the IEC 61131-2 standard. Each input voltage clamping block protects the module input against electromagnetic interferences such as those described in the IEC 61131-2 standard and IEC 61000-4-2 (ESD), 4-4 (transient burst), 4-5 (voltage surge) standards. The supply input is also designed with such a protection structure. Table 5.
