Revisiting the High Current Card
When we introduced the HC64 (High Current 64 Pin Input/Output) board, we were making an alternative product that solves a number of problems: operating voltage range, current draw, and power management. Thanks to good feedback from our users, today we are announcing that we are breaking the product up into three sub-products:
H64 - as low as 4 ohms per pin, up to 23 volts power. This card is ideal for most unit instruments and most direct electric installations. This card is only available in positive polarity (red card).
HV64 - as low as 15 ohms per coil at up to 50V. This card is good for sites with high voltage requirements. Voltage regulators, FETs, and all supporting circuitry are beefed up to support higher voltages. This card is only available in positive polarity (red card).
HC64 - this is the card we have been shipping, slightly modified. This card is now rated for up to 23 volts DC, as low as 3 ohms (at 23 volts) and 2 ohms at 14 volts. This card is available in both polarities (red for positive, black for negative). This is the card most appropriate for slider motor control, LED light loads, and other potentially high current applications.
All three variants of the board have the active on-board power management, passive power protection, and full input circuitry, making them proper IO cards. These boards are fully compatible with all Opus-Two controllers of any age, and are all available now. The HV64 and negative polarity HC64 are built to order, but the H64 and HC64 are in stock, available today.
