Core Functions

• Real-time acquisition of 16-channel standard analog signals

• Signal conditioning, filtering and A/D conversion for data transmission

• Galvanic isolation to resist electromagnetic interference and protect internal circuits

• Support dual-card redundant operation with automatic switchover upon failure

• Plug-and-play, automatically recognized by the system after installation

Application Scope

• Control cabinets of Honeywell TDC3000 and TPS distributed control systems

• Process industries such as chemical, power, metallurgy, oil and gas

• Field measurement points with 4-20mA and 1-5VDC signal requirements

• Replacement, backup and expansion of legacy DCS system components

Operation & Maintenance Instructions

• Install the card into chassis slots only when the system is fully powered off

• Verify LED status after power-on to ensure normal operation and communication

• Conduct regular dust removal and inspection on interfaces and wiring terminals

• Keep the module away from strong electromagnetic interference and damp environment

• Prepare spare cards for critical loops to reduce system downtime risks
