16-Point Vac Discrete Input Module

A separate connection to L1/+Vdc is needed when the module is used in an ungrounded ac control circuit. Input operation is unaffected by this connection. However, for ungrounded ac systems using ground fault detection circuitry, this connection balances the system and prevents erroneous ground fault indications.
