Calrec WY5858 GPIO (8 In/8 Full Changeover Out (D-Type))

Calrec Hydra2 WY5858

GPIO, 8 In/8 Full Changeover Out (D-Type)

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.

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 from any Apollo/Artemis/ Summa console which has been granted access.

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

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 opt 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 above right (or below if viewing this page on a mobile device).

GP Outputs
The WY5858 version provides 8 changeover relays with access to both the normally open, and normally closed contacts for each.

A closure pair is achieved by wiring one leg to either NO or NC and the other leg to a common pin for that specific relay.

If external equipment requires a ground for activation, rather than a closure, the common pin for that relay should be connected to a ground from the external equipment.
