4. Functionality
The Axiom AX755 functions as an interface module that bridges digital control signals and field-level devices. The 16 optically isolated digital inputs receive signals from sensors, switches, or external logic sources. Each input channel is electrically isolated from the system logic through optocouplers, ensuring that voltage transients or ground potential differences do not propagate into the control circuitry.
The 8 relay outputs act as electrically isolated switches, allowing the control system to activate or deactivate external devices such as solenoids, lamps, contactors, or alarms. Each relay output can handle moderate current loads, making the AX755 suitable for both signal-level and low-power actuation tasks.
Use Cases and Applications:
- Industrial automation and process control systems
- PLC (Programmable Logic Controller) I/O expansion
- Machine control panels and relay interface boards
- Data acquisition and monitoring systems
