### 4. Functionality

The W‑M1B112 functions as a remote analog input node in an RS‑485 Modbus network. It converts up to 16 voltage signals from field sensors or transducers into digital data accessible by a host controller (PLC, PAC, or SCADA system). Each channel’s range and scaling can be configured independently via Modbus registers or Advanio’s configuration utility.

Operation Principle:
- Field voltage signals are applied to the differential input terminals.
- Each pair of channels shares a dedicated 16‑bit ADC for precise conversion.
- The module transmits measured values to the host using Modbus RTU commands.
- The host can read raw hexadecimal or engineering‑unit data.
- Built‑in watchdogs and safety values ensure fail‑safe operation if communication is lost.

Typical Applications:
- Industrial process monitoring and control
- Remote data acquisition (DAQ) systems
- Energy management and power distribution monitoring
- Building automation and HVAC control
- Laboratory instrumentation and test benches
- Security and environmental monitoring systems

Compatibility:
- Fully compatible with Modbus RTU masters such as PLCs, HMIs, SCADA software, and Advanio’s ARIO Utility.
- Integrates seamlessly with other Wolf Series modules (digital I/O, relay, current input, thermocouple, etc.) for mixed‑signal systems.
