Description
Each DSCP70 Power Supply Connection Module permits the delivery of
power to DSCP6x modules through DIN rail mounted power-bus connectors.
An external power supply, or supplies for redundant operation, are connected
to the terminals of the DSCP70. The DSCP70 then routes the power to
the DIN rail power-bus, provides protection against power supply reversal,
provides LED status indication of correct power, inverted power connection
and presence of AC, and provides over-voltage protection.
