## 4. Functionality

The AX-IAC5 functions as an AC input interface module that detects the presence or absence of an AC voltage signal within the specified range (90–140 VAC). When an AC voltage is applied to the input terminals, the module’s internal solid-state circuitry rectifies and conditions the signal, activating an optically isolated output that transmits a corresponding logic-level signal to the control system.

Operating Principle:
1. Signal Detection: The input terminals receive an AC voltage signal from a field device such as a switch, sensor, or relay contact.
2. Signal Conditioning: The internal circuit rectifies and filters the AC signal to produce a stable DC control signal.
3. Optical Isolation: The conditioned signal drives an optocoupler, providing electrical isolation between the high-voltage input and the low-voltage logic output.
4. Logic Output: The output side generates a logic-level signal (typically 5 VDC or 24 VDC compatible) that can be read by a PLC, microcontroller, or digital input card.
5. Status Indication: An LED indicator on the module illuminates when the input signal is active, providing immediate visual feedback.

Typical Applications:
- Industrial automation control panels
- PLC input expansion modules
- Machine control systems
- Building automation and HVAC control
- Process monitoring and instrumentation
- Electrical distribution and power management systems

Compatibility:
- Compatible with standard PLC input racks and modular I/O systems that accept 120 VAC input modules.
- Can interface with a wide range of field devices, including limit switches, pushbuttons, contactors, and sensors providing AC output signals.
