Upgraded Design with Seamless Compatibility: The module's standout feature is its role as the direct step-up replacement for the older DSDI110 and DSDI110A modules . It offers optimized hardware and improved durability while maintaining full compatibility with existing systems, facilitating straightforward upgrades for legacy installations .
Flexible Input Options and Built-In Diagnostics: The DSDI110AV1 supports both dry contact (using built-in wetting voltage) and wetted contact inputs, allowing direct connection of dry relays and switches . Its channel-level diagnostics detect open/short circuits, while grouped electrical isolation improves noise immunity, simplifying field wiring and troubleshooting .
Compact and Hot-Swap Design: The module features a modular, compact form factor and supports hot-swapping within S100 I/O racks, enabling online replacement without full system shutdown . This reduces maintenance downtime in continuous industrial processes.
The DSDI110AV1 is widely used for reliable, high-density digital signal acquisition in process and heavy industries, including:
Power Generation: Unit monitoring and substation signal acquisition .
Oil, Gas & Petrochemical: Refinery valve status feedback and safety interlocks .
Paper & Metallurgy: Production line logic control and process monitoring .
Food & Pharmaceutical: Environmental monitoring and pasteurization recording .
Q1: What is the primary function of the DSDI110AV1?
A: It collects 24V DC digital signals from field devices and converts them into logic states for the controller .
Q2: Is the DSDI110AV1 a direct replacement for the DSDI110A?
A: Yes. It is the official upgraded replacement for the DSDI110 and DSDI110A modules, offering improved durability and performance with full hardware/software compatibility .
