Notes (1) The actual positions of board connectors vary from this drawing.
(2) The brake power-supply circuit is provided on the primary side (high-pressure side), so a dedicated 24-V
power supply is required. The 24-V power supply for I/O or any other power supply used on the secondary side (low-pressure side) cannot be used.
(3) To operate the alarm LED, the user must provide a circuit that uses the controller I/O output signal.
