Features:
- Designed as the DC power-entry card for Honeywell System 57 5701, 5704 and 5704F sub-racks.
- Provides separate site-supply and standby-battery paths through a removable TB1 terminal block.
- Connects rack power and supported Engineering Card plug-in options through dedicated interfaces.
05701-A-0325 is the System 57 DC input card that accepts the rack power connections through its removable terminal block.
The card accepts the normal site supply and a separate auxiliary or standby source, then distributes protected DC to the Engineering Card, backplane and approved ancillary loads.
Before replacement, verify the installed sub-rack, TB1 wiring, connected load, fuse coordination and any Engineering Card option that uses the TB2 interface.
Availability and delivery are confirmed at quotation. Provide the complete 05701-A-0325 label and installed-system details.

- Combines reverse-polarity protection, RFI filtering and fused distribution for the System 57 rack power path.
- Supplies approved ancillary equipment from the fused +24 V and 0 V output within the calculated installation power budget.
- Provides the six-terminal TB2 connection used by supported Engineering Card plug-in options.
- Primary and auxiliary inputs are diode-isolated so the higher-voltage source normally carries the load.
- Pass-through pairs allow the corresponding site and auxiliary supply conductors to continue to another connection point.
- Protected DC is routed through the Engineering Card and backplane to the installed control cards.
- Reverse-polarity protection helps protect the card from an incorrectly connected DC source.
- RFI filtering is incorporated in the incoming power path for the System 57 rack.
- FS1 provides 10 A protection for the auxiliary +24 V and 0 V output pair on TB1.
- TB1 terminals 1 and 2 provide the designated system-earth connections for the rack installation.
- The six-terminal TB2 interface is reserved for supported Engineering Card plug-in options.
- Where a 5704 rack contains more than eight catalytic cards, use the power arrangement specified for the associated Quad Relay Interface Cards.
