C64 Column-I/O
The C64 is a new form factor I/O card. Using the same robust technology featured in the H64, it arranges pins in groups of 12, has brightness control over the LEDs, and is interchangeable with all existing cards. This card can be used in consoles or chambers.
ALL NEW FOOTPRINT
The C64 is designed to fit a new form factor - columns of cards. These columns are extremely narrow, often narrower than the wiring duct would be next to them. The column cards plug end to end to make chains, and standard extender card kits connect columns together. Much like the H64, each group of 8 pins is capable of driving 6 amps total. This can be made up of any combination (6 amps on 1 pin or .75 amp on each pin), meaning this card can drive 2 ohm loads at 14 volts (for reference, 68 feet of 24 gauge telephone wire has a 1 3/4 ohm resistance). Despite the electrical arrangement of 8 pins for overcurrent protection, the headers are arranged in groups of 12. The spacing of the groups of 12 is even and aligns with many control systems over the years that have used this spacing. Existing 61 note junction cards with “female receptacles” on them will plug directly onto the C64.
INTELLIGENT
CURRENT MONITORING
The card has a high speed processor on board that is faster than some entire control systems. This processor precisely monitors current flow to each group of outputs on a header. Should an over-current situation occur the header will be shut down digitally within 5 microseconds and an LED indicator will illuminate to aid diagnostics. Each header has a separate LED to indicate the group which an over-curent occurred. Should an over-current occur, the group of 8 notes where the fault occurred will immediately shut down instead of the entire 64 notes.
