4 channel optocoupler isolation PNP/NPN to relay IO board for SCM weak control the strong electrical / TTL | Компьютеры и офис

To convert DC1.8V-DC35V level signal (PNP or NPN) to relay signals, while providing relay normally open and normally closed terminal, convenient and flexible for site .

widely used PLC inputs and outputs , level shifting and signal filtering, and strong power MCU control , microprocessor controlled high-current , high-power equipment , PLC DO port control relays, etc.

fully opto-isolated , not only to isolate the electrical signal , but also to eliminate a substantial common mode interference , to improve the stability of industrial equipment plays a key role .

Features:

1. NPN or PNP input,  relay output (normally open + normally closed)

2. lower speed ( relay 100HZ)

3. suitable for small signal to control large power devices

Typical applications for this product wiring diagram shown below, the input and output signals can be PLC, can also be single-chip, ARM, DSP and other digital circuit signal.
