YXI115B is an analog data acquisition module designed for the S100 I/O rack; it collects field process analog signals and transmits them to Advant controllers, such as the AC460.

Featuring multiple analog input channels, the YXI115B supports a variety of standard industrial analog signal types. The module includes built-in signal filtering, range configuration, and wire-break detection capabilities. Channel-to-channel isolation suppresses common-mode interference. Before use, parameters such as signal range, filtering, and alarm thresholds must be configured via the Advant MOD300 engineering station software. It connects to the AC460 controller via an S100 interface module linked to the parallel I/O bus; the bus can be extended up to 500m, with a maximum copper bus length of 12m. Detailed specifications are as follows:

- Power supply: 24 VDC (via rack backplane)

- Operating temperature: 0 to +60°C (inside the cabinet)

- Storage temperature: -40 to +85°C

- Protection rating: IP20 (when installed in the control cabinet rack)

- Mounting: S100 sub-rack backplane slot; Euro-style backplane connector

- Supports hot-swapping (live module replacement without system shutdown)

The entire S100 I/O system supports live hot-swapping, allowing module replacement without stopping the process—a key advantage of the Advant MOD300 system.

Key industries for the Advant MOD300—and the primary application environments for the YXI115B—include:

1. Thermal power plants (auxiliary control systems for boilers and steam turbines)
2. Pulp and paper industry (DCS for pulping and papermaking lines)
3. Petrochemical and refining facilities
4. Retrofitting projects for older cement and metallurgical production lines
