*Atenção: as imagens são meramente ilustrativas.

This relay module uses the industry's top quality subminiature two-way isolation optical coupling, strong anti-interference ability and stable performance.

  • Trigger current: 3mA
  • Working voltage: 5V

The user can choose the relay control level, it can be a high level off and also can be low level off.

Module contains a limited flow resistance, can directly use the power supply with negative control, you can also use the MCU I/O control.

On the interface module control side: there are 4 lines, all interfaces are terminal blocks for easy connection
1. DC + : external DC power anode (5V, 12V and 24V module selection)
2. DC - : external negative DC power supply
3. VREF, photoelectric isolation reference ground control end

Note:

  • If using high level control: this signal is connected in the user control panel power of the cathode
  • If the low level control: this signal is connected on the user control panel power supply of the anode

4. CH1: relay control interface.

Note:

  • If VREF to connect power negative: this port high level (relative to VREF) relay and accordingly
  • If VREF receive positive: this port low level (relative to VREF) relay and accordingly
  • Isolation on relay module is in order to adapt to a poor electromagnetic environment. If you want to achieve complete isolation effect, the power of the user control panel (i.e. connect VERF reference power) and relay module power supply power supply (DC + / DC) should be separate. If use only one power supply will lose the isolation effect.

Relay output: there are 3 line interface, all interfaces are terminal blocks, easy connection
1 NO: relay normally open interface, relay and impending, before and after absorption and COM sub
2, COM: relay public interface
3, NC: relay normally closed interface, relay and off with COM nipple, before and after the impending

 

Module size: 6.0x3.0x2.5cm (Length x Width x Height)
