 NEW OPPB V3 : Optical isolated parallel board

Specification

• New redesign with surface mount components
• Uses 2 kV high speed isolator chips on all signals.
• Has 20 mA drive current on all outputs and low impedance inputs to reject noise.
• Charge pump logic circuit gated to all outputs for maximum protection.
• High voltage pre-regulator circuit allows up to 70V power supply input. LED indicators for power, charge pump active and relay signals.
• On board DC/DC convertor unit
• Spare 5 & 12 volt output power connections to power external sensors etc .
• All Inputs have built-in pull-ups to minimize external wiring.
• Reverse power polarity protection.
• Double buffered charge pump and step signal lines for computers with weak drive signals.
• Relay 1 & 2 are rated at 10 Amps at 240V AC and are linked to charge pump circuit to prevent false activation.
• Several ground terminals.
• Slightly smaller dimensions than original, 98 mm wide, 107 mm height
