2-way 5V/12V/24V Optocoupler Isolation Relay Module for PLC

SKU: LC-Relay-PLC-2R

Overview
Relay isolation drive control module,  the core is electronic control devices relay，there are control system ( called  input  loop) and controlled system (called  output  loop), Essentially an "automatic switch" that uses a small current to control large currents. This design have output signal indicator prompt,adopt dual power supply selection and optocoupler design, enhance anti-interference and isolation performance. can be used for signal amplification of MCU ,PLC, industrial computer and other equipment.
 

Function features
1.Adopt HONGFA relay, performance are stable and reliable.
2.Compatible with positive and negative control input modes.
3.Each channel have one indicator prompt, More intuitive understanding of product performance.
4.Each channel adopt Optocoupler isolation, enhance anti-interference and isolation performance.
5.At the same time supply power and IN control terminal was independent control.
6.Module adopt standard “DIN”Rail mounting design, The installation is convenient, fast and stable.
