Allen-Bradley 56RF-IN-IPD22A EtherNet IP Interface Block

The Allen-Bradley 56RF-IN-IPD22A EtherNet/IP Interface Block is a dual‑channel HF RFID interface that connects two 13.56 MHz RFID transceivers to an EtherNet/IP network, enabling read/write operations from a Rockwell Automation controller. It provides two RFID transceiver ports and two discrete 24 V DC inputs (2In/0Out) with no discrete outputs, and it operates as an EtherNet/IP interface block at 10/100 Mbps in either full- or half‑duplex mode. The module measures roughly 179 × 37 × 43.25 mm (7.05 × 1.46 × 1.70 in) and is powered by a 24 V DC auxiliary supply with up to 4 A auxiliary current. Each RFID transceiver port can supply up to 100 mA at 24 V DC, while input device power per I/O port is up to 5 mA at 30 V. The 56RF family is documented as RFID Interface Blocks for high‑frequency RFID systems, with the IPD22A model specifically identified as “2 Port + 2In/0Out” in product literature and cutsheets. Typical applications include RFID‑enabled manufacturing lines for part and asset tracking, serialization, and process validation, where tagged items passing through stations are read or written by the transceivers and data is conveyed to the PLC over EtherNet/IP.>
