Calrec Hydra2 WY5859 GPIO (8 In/16 Out (D-Type)

Calrec Hydra2 WY5859 GPIO

GPIO cards can be fitted to provide General Purpose interfacing for logic control such as remote / fader starts for playback devices, triggering autofades on a control surface, and much more.

This is a one slot wide module. Inputs and outputs are all on 1 x female 50 pin D-type connector.

Access to each general purpose input and output can be given to any console on the Hydra2 network.

The function of each general purpose input and output is configurable and assignable via Apollo/Artemis/Summa console's which have been granted access.

LEDs
The Status LED strobes to indicate that the local software is running. The LED illuminates solidly when connection is established to the Hydra2 Interface Module in the same modular I/O chassis.

GP Inputs
8 opto-isolated inputs allow for remote control of console functions. Applying between 3 and 50 Volts, AC or DC across the + & - pins of the opto will trigger them.

If using a dry closure to trigger a GP input, note that the incoming closure should be wired to one side of an opto input only. The other side of the opto should be pulled up by linking it to the 5V pin on the connector. The other side of the closure should be wired to the 0V pin. An example of wiring a closure to GP input #1 is shown on the previous page.

GP Outputs
The WY5859 version provides 16 normally open contact closure pairs.

If external equipment requires a ground for activation, rather than a closure, one side of the relay should be connected to a ground from the external equipment and the other side of the relay used as the trigger.
