  3. Connection
  4. Connection to optocoupler (with external supply voltage)

Connection to optocoupler (with external supply voltage)

For connection to inputs with large input resistances, an external supply voltage (up to 24 V) can be used with the EJ2521-0224 in order to create the necessary current.

Connection to optocoupler (with external supply voltage) 1:
EJ2521-0224, wiring with external power source
Note
EJ2521-0224 ground potential

In the case of the EJ2521-0224 module the outputs -A and -B must be connected to the GND_L_O1_O2 (pin 23) in order to avoid damage to the module (see fig. EJ2521-0224 - connection)!
