Product Performance
High reliability:
Optical isolation design can effectively suppress electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring signal transmission stability.
Support channel level diagnostic function, which can monitor input status in real time and display fault information through LED indicator lights.
Flexible configuration:
Supports multiple wiring methods (such as single ended and differential), and can be flexibly adjusted according to on-site needs.
Compatible with DeltaV system’s redundant architecture, it can work in conjunction with other I/O modules (such as VE4002S1T2B5 discrete output card) to build a high availability system.
Quick response:
The scanning rate can reach 0.25 milliseconds (16 channels), suitable for control scenarios that require high real-time performance.
Easy to maintain:
Plug and play design, supporting online module replacement without affecting system operation.
The modular structure facilitates fault location and spare parts management.
