GPIO optional board

Extend the ACCURET+ position controllers with additional I/Os for fast, configurable, and real-time interactions with the machine process.  The GPIO optional board creates a direct bridge between external devices (camera, laser, etc.) and the control core; eliminating latency, bus delays, and synchronization errors that typical I/O modules would introduce.

The GPIO optional board adds fast and flexible I/O capability directly inside the ACCURET+ position controller. Installed in the controller’s optional slot, it greatly extends functionality while requiring only 25 mm of additional rack space.

Within this compact footprint, ETEL packed eighteen configurable digital I/Os (selectable direction and voltage: 3.3, 5 or 24 VDC), four analog inputs and four analog outputs
(±20 V, 16 bits). This allows seamless integration of a wide range of external sensors or process triggers.

A redesigned connectivity concept with robust industrial connectors adds a practical, user-centric advantage that installers and integrators will appreciate. Separate, dedicated cables for digital and analog channels make wiring cleaner, safer and more modular.

Above all, the true value of the GPIO optional board lies in being mechanically and electrically integrated inside the ACCURET+ controller. Signals are sampled and updated at the same 20 kHz frequency as the position loop, enabling true in-loop reaction for
time-critical events such as camera triggering or laser activation.

Characteristics

  • 18 configurable digital I/Os, individually selectable as input or output
  • Digital I/O voltage levels configurable by banks of 3 I/Os: 3.3, 5 or 24 VDC
  • Optional external 24 V supply input for increased DOUT driving capability (up to 3 A total).
  • 4 analog inputs: ±20 V differential (40 V span), 16 bits
  • 4 analog outputs: ±20 V differential (40 V span), 16 bits
  • All I/Os sampling and update frequency: 20 kHz (synchronized with control loops)
  • Connectivity: 5x iX connectors for simple and robust cabling

Here are the key features:

Signals are sampled and updated at 20 kHz, the same rate as the position loop, enabling real-time reaction for time-critical events related to process execution.

The board installs directly inside the ACCURET+ controller, adding only 25 mm to its width while expanding functionality dramatically.

Eighteen configurable digital I/Os and four analog inputs/outputs, selectable in direction and voltage level, adapt easily to any application need.

Robust industrial connectors with dedicated cables for each signal type simplify wiring, improve reliability, and allow partial disconnection without system downtime.

Two customizable user LEDs allow creation of personalized blinking patterns or status indicators, immediately visible from the front panel. This enables quick visual feedback simplifying maintenance and troubleshooting.
