Mechanical Relay

Description

Mechanical relay are present on OI-RelayHP module.

Characteristics

Relay specifications
Requirements	Value	Remark

Isolation	1500VDC

Code examples

The example code above demonstrates how to set the relay on an OI-RelayHP module. Note that normally closed (NC) output will be disconnected from ‘COM’ when you set the relay value to ‘HIGH’

#include "OpenIndus.h"
#include "Arduino.h"

OIRelay relay;

void setup(void)
{
    /* Nothing to do in setup */
}

void loop(void)
{
    /* Activate all */
    relay.digitalWrite(RELAY_1, HIGH);
    relay.digitalWrite(RELAY_2, HIGH);
    relay.digitalWrite(RELAY_3, HIGH);
    relay.digitalWrite(RELAY_4, HIGH);
    delay(1000);

    /* Deactivate all */
    relay.digitalWrite(RELAY_1, LOW);
    relay.digitalWrite(RELAY_2, LOW);
    relay.digitalWrite(RELAY_3, LOW);
    relay.digitalWrite(RELAY_4, LOW);
    delay(1000);
}
