10.2 24 Volt I/O Connections
Turn off system before connecting to the LOGIC I/O
port. There may be risk of damaging the controller.
•
24Vdc Supply:
The internal 24Vdc power can
supply up to 1 amp.
•
Inputs:
Inputs are a sinking configuration with the
common connected to the ground pins. 24Vdc is
logic ON and 0Vdc is logic OFF.
•
Outputs:
Outputs are normally open relay
contacts. The relays are rated for 24Vdc, 1 amp.
NOTE:
If Outputs are driving an inductive load, such
as a solenoid or large relay, it is recommended to
add a diode in parallel with the load to prevent
voltage surges.
