Description

Calrec Modular I/O

Modular I/O boxes are 3U rack-mount enclosures with 20 I/O card slots that can be populated with a mixed range of I/O cards, allowing for a custom selection of I/O quantities and formats.

Modular I/O boxes connect to a Hydra2 network in the same way as Fixed Format I/O. Multiple modular I/O boxes can coexist on a Hydra2 network alongside fixed format I/O if required in order to make up the total quantity of I/O in the format and location it is needed.

Power

Each modular I/O box is fitted with 2 x rear mounted AC PSUs, each with their own AC IEC input operating from 100–240V AC 50/60 Hz. Either PSU can power the whole box, two are fitted in order to provide redundancy.

Where possible, each PSU should be fed from a separate AC source in order to provide redundancy against both PSU failure, and external AC mains loss. Input power (maximum) 100–240 VAC, 1.52–0.68A RMS, 50/60 Hz.


Earthing

Chassis earth studs are fitted to each PSU cover. These should be connected to ground using earth cable of at least 6mm 2 cross-section (10 AWG).

Air-flow and mounting

The unit is a 19" rack-mount enclosure designed for mounting into standard equipment bays. Rear/side supports should be considered in order to avoid excessive stress on the front racking angles, particularly if fitted into a mobile installation. A recessed air-intake grill runs across the bottom of the box.

The box can be mounted directly under, or on top of another unit or surface—the recessed design of the intake allows sufficient air to be drawn in from the sides (see diagram) to cool the box. Both side facing inlets should be left unobstructed.

Low noise fans fitted to the PSU modules pull air through the box, venting to the rear. To minimize fan noise and longevity, modular I/O fan speed is varies depending on the temperature within the box.

Hydra 2 I/O Cards - Digital - Analogue - SDI - GPIO - AoIP

A wide range of analogue, digital and audio networking cards can be installed into the Calrec Hydra2 Modular chassis, available in the following categories;

For a full list of supported cards, see the Supported Cards tab above.


Hydra2 interface card

The central card slot of a modular I/O box is reserved for a Hydra2 interface card. This card connects the I/O to a Hydra2 network. Unlike fixed format I/O, the Hydra2 interface connectors are on the front of the modular I/O box.

Two Hydra2 interface ports are provided for redundancy - port 1 connects to a primary Calrec router, port 2 to the secondary router in the same core. The Hydra2 interface is via pluggable SFP modules, the correct type of SFP should be ordered to match the installation requirements - Cat5e copper, singlemode, or mulitmode fibre. Please refer to the section on SFPs in the Installation manuals for more detail.

For an overview of the modular I/O cards currently available, see the Supported Cards tab. More detailed information for each product is provided on the individual product pages for Calrec Hydra I/O cards.
