Part Details:

STEVAL-IFP008V1 Demonstration board for the CLT3-4B current limited termination Data Brief Features For IEC61131-2 type 1 and 3 inputs 4 input channel topology Fully integrated internally fixed current limiter Optocoupler output drive Wide range supply voltage and temperature operation STEVAL-IFP008V1 Description The CLT3-4B is a quadruple logic input termination for sensor or mechanical switch The most important aspect of the CLT3-4B is the interfaces. It is designed to work in 24 VDC electrical protection and susceptibility its brings to applications such as PLCs (programmable logic the application. The CLT3-4B implements efficient controllers), PACs (programmable automation protection diodes on each input and supply volt- controllers) and distributed I/O systems used in age line. Serial resistors ensure a higher level of factory automation. susceptibility of the entire input module. The device optimizes the input VI characteristic to Thanks to its compact TSSOP20 package CLT3- reduce its power dissipation. This becomes 4B device occupies very little space on the PCB critical when the application cabinet or housing compared to an equivalent discrete solution. requires higher protection levels such as IP65 and IP67. These closed cabinets are used in various automated lines including the food and chemical industry. The power dissipated inside the module is very limited as there is usually no air circulation inside the box. The current limitation also reduces the power losses in the sensor.
