Adafruit Industries 8-channel Bi-directional Logic Level Converter - TXB0108 - Micro Center

Features: The module can convert input 5V level to 24V level , or convert input 24V level to 5V level . It can also convert 5V to 5V, or 24V to 24V level, and isolate input and output 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 , 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. 24Voutput is OC output (NPN collector open circuit output), if you want to test output, it must add resistor, normally use a 10KR resistor. You can use 4pcs M3 standoffs(not included) to install it.
