Quantum DIO is implemented over a Modbus Plus network. The CPU or NOM modules may be the network head via their Modbus Plus ports. Quantum DIO Modbus Plus drop adaptors are specifically designed to link Quantum I/O modules to the head via twisted pair shielded cable (Modbus Plus). The DIO drop modules also provide the I/O with power (maximum 3A) from a 24 VDC or a 115/230 VAC source. Each DIO network supports up to 63 distributed drops using repeaters.
NOTE: In the DIO rack with 140 CRA 211 x0 module, 140 DSI 353 00 module must not be used.
