Balogh MELS-30 RFID Multi-Protocol Control Board

Balogh MELS-30 RFID Multi-Protocol Control Board is a single‑channel controller designed to read and write Balogh OP tags with 64‑byte and 94‑byte data blocks. Commonly documented as the MELS-30/P variant, this module provides RS‑232, RS‑422, and RS‑485 serial interfaces for flexible integration with industrial controllers or automation equipment, and it operates from a 24 VDC supply with two parallel outputs for signaling or control tasks. The board is intended for Balogh RFID systems requiring multi‑protocol operation in a compact form factor suitable for mounting in control cabinets or on compatible DIN rail assemblies. Typical applications include part tracking and inventory control on production lines, equipment authentication, and process automation where Balogh OP tags are read and written by a dedicated control device. The MELS‑30 family is defined as a single‑channel control board supporting OP tags in the 64‑byte and 94‑byte ranges, offering a straightforward solution for integrating Balogh RFID tagging into existing industrial architectures.
