Position: High-density Hybrid DI/DO Switching Station, Standard 24 configurable digital inputs + digital outputs, DIN rail on-site nearby arrangement, considering signal acquisition and load driving

Channel Hardware Configuration (24 Programmable Channels)
Overall 24 channels can be software-divided into DI inputs and DO outputs, channels are electrically isolated in groups
1. DI Digital Input
Power Supply Circuit: 24 VDC (18–32 VDC), compatible with passive dry contacts (valve limit, pressure/temperature switches, emergency stop button, float level)
Conduction Threshold: >16 VDC as ON, <6 VDC as OFF, single channel loop current 4–7 mA
Built-in LFD Open Circuit Detection, Ground Short Circuit Diagnosis, single channel fault isolated independently without affecting the entire board operation
2. DO Digital Output (Solid State Transistor Output)
Drive Voltage: 24 VDC, single channel rated 0.3 A, maximum peak 0.45 A, capable of driving small relays, solenoid valves, alarm indicator lights
Short Circuit Self-lock Protection, Communication Loss can be preset as safe state (keep / disconnect), compatible with ESD Safety Interlock Circuit
Optical Isolation 500 V, Suppressing Ship Ground Loop Potential Difference Interference
Channel Allocation Reference
Typical Engineering Allocation Scheme: 16 DI + 8 DO; Can be customized for a maximum of 24 DI or 24 DO full configuration

Dual Redundant SPBus Field Bus
SPBus (Serial Process Bus) Private RS485 Manchester Bus
Transmission Rate 2 Mbps, A/B Dual Bus Hot Standby Redundancy, single bus breakage module continues to work
Interface: Double 9-pin D-SUB Male Connector, Electrical Isolation with Voltage Rating 500 V
Upstream Connects to RAIT400 Local Controller or RCU501 System Master Controller, as a Distributed IO Node to Access the System Main Network
