This level converter is mainly used for PLC or MCU interface matching with other circuits, external circuit signal level conversion circuit, or other level conversion between control circuits. This module can convert 8-channel signals at the same time, using isolation chip of 10MHZ bandwidth, which can effectively guarantee speed and integrity of signal. Features: The module can conve rt input 5V level signal to 24V level signal, or convert input 24V level signal to 5V level signal. It can also convert signal 5V to 5V, or 24V to 24V level, and isolate input signal and output signal through optocoupler, which can improves anti-interference ability of circuit. Input level can be set by DIP switch, 24V level output is NPN OC output, output current is 100mA. It has conversion and amplification circuit, good wave, strong driving ability. Compatible with a common-cathode or common-anode input connection, matching European and Japanese PLC interface standards. Compatible with AC/DC input power supply interface, designed with power indicator light. When output is selected as 24V level, it is NPN OC output, with maximum 1A load capacity. 24Voutput is OC output (NPN collector open circuit output), if you want to test output, it must add resistor, normally use a 10KR resistor. When converting signal to 24V level, the power supply of input should be 24V. When converting signal to 5V level, the power supply of input can be in between 7V-35V. You can use 4pcs M3 standoffs(not inc luded) to install it.
