This level converter is primarily used for PLC or MCU interface adaptation with other circuits, external circuit signal level conversion circuits, or other level conversions between control circuits. This module can convert 8-channel signals simultaneously, utilizing an isolation chip with a 10MHZ bandwidth, effectively guaranteeing signal speed and integrity. Features: The module can convert a 5V input signal to a 24V level, or a 24V input signal to a 5V level. It can also convert 5V to 5V or 24V to 24V levels, and isolate input and output signals via optocouplers, enhancing the circuit's anti-interference capability. The input level can be set using a DIP switch. The 24V level output is an NPN OC output with a 100mA output current. It features conversion and amplification circuits, providing good waveform and strong driving capability. Compatible with common cathode or common anode input connections, matching European and Japanese PLC interface standards. Compatible with AC/DC input power supply interfaces, designed with a power indicator light. When the output is selected as 24V level, it's an NPN OC output with a maximum load capacity of 1A. The 24V output is an OC output (NPN collector open circuit output). If you need to test the output, you must add a resistor; a 10KR resistor is typically used. When converting signals to 24V level, the input power supply should be 24V. When converting signals to 5V level, the input power supply can range from 7V-35V. You can use 4 M3 standoffs (not included) for installation.
