The Allen-Bradley 1770-XYC is also cataloged as the 1770-XYC AB PLC-5 Battery, providing lithium-cell backup power for retained PLC-5 memory data during primary system power loss.

Model Identification

The supplied documentation identifies 1770-XYC as a dry-cell lithium battery with a 2-pin connection. No additional suffix breakdown is specified in the provided technical data.

Physical and Electrical Data

PLC-5 Memory Retention Characteristics

The 1770-XYC is a passive backup power component rather than an I/O or communication module. Its electrical function is associated with maintaining stored PLC data when the controller's normal power source is unavailable.

The 2-pin connection provides the electrical interface between the battery assembly and the applicable PLC-5 hardware. Battery replacement should preserve correct polarity and connector engagement. No voltage, capacity, discharge current, or service-life value is specified in the supplied information, so these parameters are not assigned here.

Ordering Configuration

• 1 x Allen-Bradley 1770-XYC lithium dry-cell battery
• 1 x 2-pin battery connection interface as integrated with the supplied battery assembly
• No separate mounting kit or adapter is identified in the supplied technical data

Installation and Handling Notes

• Isolate the applicable PLC equipment according to the site maintenance procedure before battery replacement.
• Verify the existing battery connector and mating socket before installation.
• Maintain the original polarity and connector orientation.
• Avoid shorting the battery terminals during handling or installation.
• Keep the battery leads clear of sharp edges, moving components, and high-temperature surfaces.
• Do not connect the battery directly to external loads or substitute an unspecified battery chemistry.
• Follow applicable lithium battery handling and transportation requirements for the installation location.

Technical FAQ

• What type of battery is the 1770-XYC?

  The supplied data identifies it as a dry-cell lithium battery intended for Allen-Bradley PLC-5 hardware.

• How many electrical terminals does the battery have?

  The specified connection is a 2-pin interface. Polarity and connector orientation should be maintained during installation.

• Is the 1770-XYC an I/O module?

  No. It is a battery component associated with PLC-5 memory retention and does not provide analog, digital, or communication I/O.

• Does the battery consume power continuously?

  It is a passive battery device. A specific discharge current or power-consumption value is not provided in the supplied specifications.

• What is the specified battery chemistry?

  The supplied product information identifies the battery as lithium dry-cell construction. No detailed cell chemistry or capacity is provided.

• What is the physical weight of the 1770-XYC?

  The supplied technical data lists a product weight of 0.02 kg. The stated shipping dimensions are 4.5 x 1.5 x 1.5 cm.

• Can the connector polarity be changed during installation?

  No. The specified 2-pin connection should be installed with the original electrical polarity and connector orientation preserved.

• Is an operating temperature range specified?

  No operating-temperature value is included in the supplied data. The battery should therefore be installed according to the applicable equipment and battery handling requirements.
