DSCP70
Power Supply Connection Module for DIN Rail Power Bus
Description
DSCP
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.
uFeatures
• Delivers Power to DSCP6x Modules Via DIN Rail
• Two Independent Inputs Allow Redundant Power
• LED Indication of Power Supply Presence
• LED Indication of Reversed Power Connection
• 19.2 to 30VDC Power
• Spring Cage Clamp Connection
• Compact 6.2mm DIN Housing
• CE Compliant
