4. Functionality
The Axiom AX5064O functions as an isolated digital output interface card for PC-based control systems. It connects to the ISA bus of a host computer and provides 64 individually controlled output channels. Each channel operates as an open collector output, allowing it to sink current from an external power supply (5–24 VDC) to drive external loads such as relays, lamps, solenoids, or other digital devices.

How It Works:
- The host computer sends digital output commands through the ISA bus.
- The AX5064O translates these commands into corresponding output signals on its 64 channels.
- Each output transistor switches the external load circuit on or off, depending on the control signal.
- Electrical isolation ensures that any voltage spikes or ground potential differences on the output side do not affect the host system.

Use Cases and Applications:
- Industrial automation and process control systems
- Machine control and equipment interfacing
- PLC and SCADA system expansion
- Signal switching and relay control
- Test and measurement systems requiring multiple digital outputs
- Laboratory automation and data acquisition setups
- Control of indicator lights, alarms, and actuators

Compatibility:
- Compatible with standard AT/ISA bus industrial PCs
- Works with Axiom’s software drivers and libraries for DOS, Windows, or Linux (depending on system support)
- Can interface with external relay boards, terminal blocks, or custom wiring harnesses via D-sub or flat cable connectors
