7.2.3MXP POWER SUPPLY

The raw power to the board is supplied from the 24VIN terminal (via D36) or the 24VOUT terminal (via D34), or both, depending on the Loop conditions.

This voltage "+V" is smoothed and maintained by reservoir capacitors C65, C66, and C71, which store sufficient charge to maintain the circuitry under transient loop fault conditions.

From "+V" the following supplies are derived:
