Frequently Asked Questions (FAQ)

• What is a DIO Head-End Adaptor? It is the master communication module that connects a Quantum PLC rack to a network of remote I/O drops via Modbus Plus.
• What is the difference between the two ports? The RS-485 port is for the multi-drop Modbus Plus network. The RS-232 port is for a simple point-to-point connection.
• What remote I/O is it compatible with? It is designed to work with Quantum remote I/O adaptors like the 140CRA21110 and 140CRA21120.
• What does "30 I/32 O words" mean? It can map 30 words (480 bits) of input data and 32 words (512 bits) of output data between the CPU and the remote I/O network.
• What is the conformal coating for? The Humiseal coating protects the board's circuitry from humidity, dust, and corrosive atmospheres, extending its life in harsh environments.
• Can it be used in hazardous areas? Yes, its FM Class 1 Division 2 certification allows its use in certain hazardous locations.
• Is it programmable? No, it is a communication hardware module. Configuration of the network is done within the Quantum PLC programming software (Unity Pro).
